My first one of the season- Corydalis wendelboi ssp wendelboi
-
David,
Thank you so much for the photograph of C. wendeloi. I hope you post more Corydalis photos as your season progresses. Here in interior California (very hot in the summer) I'm very much isolated from the horticultural world and more or less the last stop for interesting plants. I grow C. flexuosa and that is about it, however I believe that other species would do well here. Anyway, until more comes my way I can enjoy the photographs and learn something too. Thank you so much.

Robert, although I have a few species I'm very much a beginner with Corydalis and wouldn't be able to teach you much at all. It won't be long now though before the really good growers begin to show their pictures and in the meantime Ian Young's Bulb Log will offer you a vast amount of information (you can search it on "Corydalis )

nice plant David, great to see the first signs of a spring to come
-
David,
Thank you for all the good words. I believe, if we are open, we can learn from everything! The Bulb Log, more or less, got me started with the forum. Mr. Young does us a huge service. It must be a labor of love. Maggi's efforts can not be forgotten either, her beneficial involvement in the forum is very evident.
I look forward to more Corydalis postings in the future.

In effect, Ian and Maggi as a unit ARE the Forum. ;D Oh well, there are a few others involved too, like a few thousand posters and lurkers but I can't imagine anyone else in the world who could have made our Forum such a friendly, user-friendly place where everyone is welcome and they don't mind our particular foibles. I know many have left others forums (fora?) because the rules were so strict they stifled open discussion and left participants with such a narrow focus that the life of that particular forum became boring very quickly and one felt inhibited form expressing a genuinely held opinion. Long live Maggi and Ian! ;D ;D ;D
-
Thank you Lesley for the good words about the forum!!
I hope to contribute as I can, however the garden here is still sleepy.
Robert
-
Here, here to Lesley's endorsement of Maggi and Ian. Lots of information, great research (how do you find all those links, Maggi?), care and concern for the forum members intermingled with plenty of fun. I'm hooked!
-
Maggi does all the research and finds the links by not going to bed at all. She was working madly at her computer when I went to bed and was still there when I got up next day. I don't know how she manages it as she still looks fresh as a daisy - or a rhododendron - no matter how long her hours. ;D

Corydalis haussknechtii

(http://farm8.staticflickr.com/7332/11935003225_73aedea1f9_o.jpg)
One of the bulb-belt species and one of the earliest to flower. This is a Kurdish endemic being found in Turkish and Iraqi Kurdistan.
The flowers are white or very pale lilac with dark red-purple tips to the inner petals.
Not a plant to set the heather alight but it does have some quiet charm when viewed up close.
-
Steve,
C. haussknechtii looks nice in the photographs. There are, more or less, no Corydalis in our garden now. I have another batch of seed started so maybe this will change in the future. In the mean time, I enjoy seeing what others have growing.
Robert
-
These are very early flowering corydalis David and Steve. Nowhere near flowering here, they start after most of the snowdrops are over.
-
My first one of the season- Corydalis wendelboi ssp wendelboi
Wow that is early and from the picture growing in the garden? Have you had them long David? There are so many pictures of gorgeous Corydalis on this site it is difficult to know which ones to try next.
And a great photos Steve.
-
Bought last August from Augis Bulbs (he has a substantial listing of Corydalis and supples high quality bulbs). It's put on a bit of growth since I took the picture so I'll try to get an update this week.
-
I have Corydalis Kingfisher. It has been in flower since August and was still looking good in the middle of January. In the last few days it has taken a battering from the wind and heavy rain.
-
During a garden walkabout the other day, I noticed that our Corydalis elata was showing some green leaves, having emerged from under a snowbank. I was about take a few photos to share, but we have been buried again by yet another Nor'Easter. Now I have more snow removal work to do!
-
The habit of C. flexuosa, omeiana and their hybrids to make overwintering foliage is a welcome one for us here. They are remarkably hardy too, coping with snow, open frost or seemingly endless rain - just great plants!

Yes lovely plants completely happy with anything our winters can throw at them, but those types are very susceptible to drying out in the summer. I grow them in pots, but any in the garden die off over the summer. The bulbous types come back each year ( of course) - I hadn't realised just how early some of them start into growth.
I dont suppose "drying out in the summer" is too much of an issue in Aberdeen? ;D ;D ;D

Not often an issue at all, no! We think we lose more plants through summer wet than winter wet. :P
-
I was out today looking for my corydalis solida but there are no signs of them yet up here. I've got one stirring in a pot though. Maybe it's all that wet you've had down there David?
-

Chris, that's interesting. I believe here in Poland we tend to have longer hot spells than you and summer drought periods may be severe. Yet, while my Corydalis flexuosa always go dormant in summer (except rare cool and wet summers) they always nicely regrow in autumn. They never repeat flowering in autumn, though. And I have very few seeds.
I believe, the key for success is watering in the drought periods (that I regularly do except vacation) + somewhat water retentive soil + naturally cool location + lack of direct sun in summer + lack of significant root competition. In my semi-woodland garden I can achieve all. My felxuosas easily survived last year's record heat - up to 38C.
-
Our C. flexuosa grow reasonably well here in hot interior California. 38C, or more, temperatures are common most summers. Everything Jacek stated above works for us.
Our plants do reseed. They also bloom in the autumn, after summer dormancy, if the weather stays cool.

Corydalis popovii
(http://farm3.staticflickr.com/2820/12390702835_a7c6e239fb_o.jpg)
-
Jacek, Robert - Thanks for the information. I do have one spot in the garden that might be OK. I usually try to grow plants that dont require regular watering over the summer and do well in my soil with just some organic matter at planting time and some mulch/fertiliser occasionally. However the colours on these corydalis are so good I am sure I could make an exception for another try with these.
Another great photo Steve.
Chris - Solida has just appeared here over the last couple of days, noses pushing through the soil but no leaves showing yet.
-

Thanks Cyril!
The Leonticoides Corydalis were one of the few groups of plants to survive the many years of neglect here when my interests lay elsewhere. Even then many of them suffered from lack of watering and as a result a few have fragmented into 2 or 3 smaller tubers.
-
Please could some one help with advice about how to propagate Corydalis Blackberry Wine. I've had it for a few years and it seems to like my shady conditions and I love it. I've not been able to find any seed and the plant does not spread at the root although the top growth is very vigorous. I'm loathe to dig it up incase I loose it. Do you think root cuttings might work? :-\
-
It keeps on spreading... Pretty even without flowers.
Corydalis elata x flexuosa

Just in case you wondered what the flowers look like. In flower from May to October.

I don't know the parentage of this plant - I believe it is thought to be a hybrid. I would have thought that a gentle lifting of the plant and division might be the best start. After all, you're going to have to disturb it quite a bit even to take root cuttings. Most of the hybrids with that sort of "look" can be divided. If you manage a single split to start with you may also get some roots to experiment with. 'Nothing ventured', and all that!

Yes that would be my approach too, but only if you can see several "growing points". Otherwise I would either leave it alone or move it to somewhere else where perhaps it would "bulk up" quicker.
It is one of those plants that I have never seen growing and from the pictures I cant make up my mind about it. What sort of soil does it grow in?
Thanks

Re: corydalis "Blacberry Wine"
Margaret,
I have no experience in propagation of this corydalis. Instead, I can refer to the book "Bleeding Hearts, Corydalis and Their Relatives" by Tebbitt, Liden and Zetterlund (2008), page 142: Corydalis taliensis ... is a perennial ... that is only marginally frost hardy. ... C. taliensis can be increased vegetatively, since the nodes of the plants often root when they come into contact with the substrate. ... Corydalis shihmiensis is similar to C. taliensis. ... The cultivar "Blackberry Wine" is offered by several nurseries in the US and can take colder climates than C. taliensis. In the wild, C. shihmiensis seems to be usually annual or biennial, but despite this the cultivar is propagated by in vitro culture. ...
My personal experience is low. While it is rated to be hardy down to zone 5 by some US nurseries or services, it has not survived the first winter in my garden.
-
In flower from May to October.
Hi Bolinopsis,
Is it your own cross of elata and flexuosa? All the plants of the flexuosa complex that I have flower once only for me (late spring), then go dormant and do not reflower in Autumn. I would like to know if this is the matter of climate or I do not have appropriate plants. I would love to experiment with your plant in my garden. Do you think it is possible?
-
Do you know the factors promoting cleistogamy in Corydalis cheilanthifolia? I have not seen nice flowers, yet. Especially in the autumn the flowers tend to be invisible. Now I try to plant the seedlings in more sunny places. May be it will help.
-
David - thank you for remembering about me.
Maggi - thank you for the encouragement. I'm a bit scared of killing it. Roots and stems are very brittle. I've tried to layer the long flowering stems but they are not having it.
Jacek - thank you for the reference and the advice. As it happens I've just sown some seed of C. taliensis and so it will be interesting to compare them, if germination is successful. It has similarities to C. Blackberry Wine below. (Sorry about very poor pics) The close up is meant to show one of the flowering stems starting to shoot which it does at some speed!
-
The problem with C. shimienensis 'Blackberry Wine' is the fact that it is self sterile, and only a single clone is propagated. When grown alongside other clones it self seeds prolifically, to the point of being a bit of a nuisance, and behaves (at least in my former Norway garden) like a biennial, or rarely as a very short lived perennial.

A few Leonticoides Corydalis in flower.
Last autumn they were moved to my greenhouse as their normal cold-frame home is leaking and in need of repair. Unfortunately this resulted in earlier watering and increased heat which has wakened them earlier than I would have liked resulting in some etiolated foliage.
Corydalis verticllaris
(http://farm4.staticflickr.com/3721/12718438895_a8e9cbccc3_o.jpg)
An Iranian species purchased from Janis Ruksans last summer.
Corydalis cryocentra
(http://farm8.staticflickr.com/7457/12718501475_419d91167e_o.jpg)
A rather variable and fairly small-flowered species from Krygyzstan. This individual has quite a striking flower and came from Jan Jilek last year.
Corydalis sewerzowii
(http://farm3.staticflickr.com/2881/12719093274_44c5b318ca_o.jpg)
This individual has the largest flowers I have ever seen on a Corydalis (though I've not seen that many Corydalis). As each flower matures the saccular end becomes increasingly yellow and loses the wrinkles whilst the post mature flower takes on a reddish hue before withering. This individual is a survivor from the mid 1990's (I subsequently lost my way and my interest in bulbs/alpines for about 15 years losing most of my plants to criminal neglect in the process!), the label is long lost so I have no idea of its provenance.
-

measurements, Steve?

Nice plants and such clear photos Steve.
Corydalis sewerzowii This individual has the largest flowers I have ever seen on a Corydalis
Perhaps it's your clone. Mine are 3.5-3.8 cm, so nothing exceptional, albeit first flowers from seed sown Sept 2011 (Vladimir Koblintsev coll., Abail, southern Kazakhstan).
-
Maggi & Ashley,
I found it rather difficult to measure!
My biggest popovii flowers (corolla) measure about 43mm but a few of the flowers on this sewerzowii are close to 46mm -the spur in both plants curves at the end.

Well grown Tony.

This Corydalis popovii is thriving on a sandy dry raised bed outside. It's been there for about 8 years.
-
Cyril did you grow your pop from seed? It's lovely...
-
Very nice C.popovii, and it is good to know how you grow it. :)
I have mostly C.solida cultivars, but I'm thinking of trying also these earlier species.
-
Cyril did you grow your pop from seed? It's lovely...
Christine, some years ago when I got interested in leonticoides Corydalis, I pollinated different clones of C. popovii and grew quite a few plants from my own seeds. Some of them are still in pots but I have a few outside which surprise me by coming up and flowering every year. I think if you get the right place (well-drained, sunny), they are not too difficult outside.
-
Very nice C.popovii, and it is good to know how you grow it. :)
I have mostly C.solida cultivars, but I'm thinking of trying also these earlier species.
Leena, the Corydalis solida cultivars are lovely at this time, but they do seed around profusely in my garden, so much so that I am having to weed them out now.
-
Wonderful show of Corydalis solida, Cyril. Do you weed out most of the purples? I started with Corydalis 'George Baker' in a pot and got lots of seedlings in the frame. I planted them out in the garden and have as many purples as reds and pinkish reds. Pale pinks are rare. I have a couple of white solidas in pots but have not planted any in the garden yet.
-
The Corydalis solida in the frame are not flowering very well this year. Maybe they dried out too much last summer. I should plant out the seedlings and just keep named varieties in pots.
The white in the last picture is Corydalis malkensis
-
Leena, the Corydalis solida cultivars are lovely at this time, but they do seed around profusely in my garden, so much so that I am having to weed them out now.
How lovely view! Here C.solida is at its best in the end of April and beginning of May. I'll post pictures when they flower.
I have had some red and pink solida cultivars now for only a few years, and I hope someday they will increase as much as with you and with Roma. :) My first solidas were purple but the reds are so much more special and give much needed color to the garden after the winter.
Last couple of years I have collected the seeds from the reds and sown them in pots, I think the first of them will flower next year.
My plan with them as with many other plants is first to buy the good mother plants and then increase them from seeds. It takes time but it is cheaper. ;)
-
I started with Corydalis 'George Baker' in a pot and got lots of seedlings in the frame. I planted them out in the garden and have as many purples as reds and pinkish reds. Pale pinks are rare.
It will be interesting to see what color my open pollinated seedlings from reds will produce. I try to keep the purples in the other side of the garden, but of course the bees fly everywhere.
I have a nice pale pink cultivar, 'Preludie', which is one of the first to come up and flower, I can already see it's buds. Another pale pink is 'Blushing Girl', but it seems to be slow to increase in my garden (and it is quite small), and I haven't looked for it's seeds.

Roma, I have been weeding out the muddy purples over the last few years but this year I am being more ruthless and am including pinks and reds. Whites are not very common and I have left these so far. Weeding them is the only way to see other plants flowering at the same time. I do come across the odd interesting colours which I mark and keep. I even found a C. malkensis purple hybrid which I am fond of. You would think that these hybrids would be more common by the way that C. malkensis seeds around but this is one of the few hybrids I have found over the years.
-
Cyril, what plants do you grow in the same beds after the Corydalis is over?
-
Cyril; do you have a picture of the malkensis hybrid? I had a single hybrid show up among a clump of seedlings in my old garden, picture below.
-
Corydalis solida from Mt Vermion Greece where they are all white. Not a good year for them here so not flowering too well.
-
Cyril, what plants do you grow in the same beds after the Corydalis is over?
All sorts of plants Leena. Bulbs include galanthus, narcissus, fritillaria, erythronium, iris etc. There are also other smaller alpines, pulsatilla and a few dwarf daphnes. The problem is that right now you can only see the corydalis as they are so dominant.
-
Cyril; do you have a picture of the malkensis hybrid? I had a single hybrid show up among a clump of seedlings in my old garden, picture below.
Bjonar, your hybrid will probably look similar to mine once the flowers are fully open.
Here are some pictures of my hybrid.
-
Can you help to identify this corydalis? I made pictures today.
[attach=1]
[attach=2]
I bought it a few years ago with the name "Corydalis Anetkas" - a name that is clearly not valid. The nursery (located in Poland) does not offer it any more and the owner did not know any other name for it.
Using the book "Bleeding Hearts, Corydalis, and Their Relatives" I provisionally identified it as Corydalis ellipticarpa.
It is relatively tall - more than 30 cm in summer. Forms pseudobulbs at the soil level built of swollen leaf bases (similar to C. Chocolate Stars, but smaller). They can be detached and replanted. Hardy in our winters. Needs continuous moisture - in droughty places dwindles and disappears. In my garden I am able to keep it only in shady location (water??) Flowers are very few. Individual flower is fairly big, yellow, but turns brown rapidly. For me - only the foliage is interesting and you can see it at its best. I have not had seeds so far
-

It's lovely! Mine was lost when I moved to China.

Certainly looks like C. ellipticarpa, a picture of it in flower would confirm it.

The best thing about my corydalis solida bed is that the bumblebees swarm all over it!

Steve, what a lovely Corydalis. I have never seen this one before.
It is on my wishlist now!
Lina.
-
Steve, Corydalis ornata is nice, but your pictures are even better.
Arisaema, thanks for info. I will show flowers when I have some. But I believe, the spring foliage is the best feature of this plant. Do you know what conditions have to be met to make it flowering? Does it need sun? Or may be it dislikes warm summers?
-
Corydalis ornata a clonal selection called "Blue Lip"
Very striking Steve. I grew one as C. turtschachinovii 'Blue Lip' (probably correctly C. ornata) for many years but eventually lost it. Did you get yours recently?
-
Cyril I purchased it a year ago from Paul Christian.
I previously had a few tubers that had "clumped up" from an initial purchase from Janis Ruksans some years back, but they dried out in the summer of 2008. It's such an attractive wee plant that I had to get another when I saw it for sale again.
-
The problem is that right now you can only see the corydalis as they are so dominant.
I would be quite happy to have this problem. :(
-
C.ornata is beautiful!
I once planted one bulb, it came up the next spring but only with small leaves and never after that. :( Could it be that it needs drier place than C.solida which does well in the same bed (and also C.turtschaninovii does well there)?
-
Leena;
I doubt it needs drier conditions than turtschaninovii, I grew it for years in my (soaking wet) S Norwegian garden...
Jacek,
Could the main shots with flower bulbs have frozen off in previous years? That happened occasionally in cold winters. It dies down naturally in summer, so the heat shouldn't be that much of an issue. I grew it in a moist spot in half shade.
-
Ornata does best in cool, moist semi-shade where it can avoid a summer baking. In our maritime climate it rises too early and can be hit with Spring frosts but I suspect that it will do well in cold continental winter climates, but be wary of late frost as the new growth seems quite sensitive.
-
Leena;

Thank you Arisaema and Steve. I will have to try it again. :)

I like Corydalis nobilis at this early stage of development. Leaves are so nice with this characteristic olive or bronzy tint (not easily visible on the picture). And the flower stalk is also nice. Later when fully developed it is still nice, but the green colour becomes "average" and the flowers are too pale for me.
It grows well for me in any spot except places covered with thick leaf mulch. Last year was the first with seeds, but I don't know if I have any seedlings, yet.
At the first picture - accompanied by Corydalis lutea that feels far too well in my garden
At the last picture - can you differentiate the leaves of C. solida Beth Evans and C. nobilis? They grow in one spot.
-
About the Corydalis ellipticarpa shown as a spring plant by Jacek. This can make an excellent display of flowers and seems to me one of the best non-tuberous species. I have three different forms from Chen Yi. Easy to grow in northern England in very large pots or open ground with deep humusy soil, with added lime and moderate amounts of fertilizer. Moist, but not wet in winter, and avoid getting too dry at any time for the rest of the year.

Two tall Corydalis, the first one is C.cava'Alba' and the second one is C.marshalliana.
-
Certainly looks like C. ellipticarpa, a picture of it in flower would confirm it.
Bjornar,
After 6 weeks the corydalis is in full bloom now. Would you be so kind and confirm if it is C., ellipticarpa?
It is now 50 cm tall. This is the first time it blooms nice and abundant for me. I even started to like the bronzy older flowers. I don't believe winter frost prevented flowering in the previous years - previous winter was even milder than the last one. I believe it just needs time to settle. It is now 4 (may be 5) years from planting. As it is a surface grower - the settlement might be prolonged due to deep planting (I always do so to prevent frost damage)
It is a stout plant - not leggy like most flexuosas for me. It clearly needs continuous moisture to grow well. Seems to be more prone to drought damage than flexuosas. Seems not to mind the shade.
Due to early growth, dense foliage and height it may outcompete spring bulbs.
Will see if seeds is set this year.
First picture at the start of flowering about a week ago.
-
Jacek
The four photos certainly look similar to ones which Magnus Liden identified (based on images) for me as C. ellipticarpa complex. I got three different forms from Chen Yi Nursery in 2005 under the names nigro-apiculata, grandifloraum and temolana. (All nonsense names!) The first two are quite similar and correspond well to descriptions of ellipticarpa, but the last differs considerably (? different species). Have attached a photo taken today of the one which am convinced is ellipticarpa.

I have one small seedling of Corydalis panda. I'm wondering if I should plant it to my woodland bed where Corydalis elata and Corydalis solida grows well or should I plant it somewhere more dry, maybe a sand bed or something like that. I don't want to lose it because I have just that one seedling.
Does anyone else grow Corydalis panda and where would you advise me to plant it?
-
Hi Lena. I think it prefers a cooler place, it grows quickly so might flower this year. It is not long lived and stored seed doesn't germinate well, the best way to keep it going is to poke the seed into the ground around the plant. I thought I had lost it but found a seedling which is now flowering well and will try to get it back to quantity again. Susan

Hi Leena Assuming you've got the real Corydalis panda, suggest planting in a large pot with plenty of humus including a small amount of lime and then placing in an open position to get the maximum sunlight. However, it probably ought to be taken into a greenhouse overwinter to avoid the risk of rotting, though the pot should not be too dry. As it comes from a high altitude, likely that the seed needs overwinter cold before germinating.

Thank you Susan and Brian. :) I bought the seeds from Holubeck December 2012 (wild collection), they didn't germinate in the spring 2013 and I thought they never will, but this spring one seed germinated so it is very valuable to me. I hope if and when it flowers it will also produce seeds as it is only one plant.
I think I will grow it first in a pot and hope it will grow fast and then think of a place for it where there is not too much wet.
I also have one seedling of Corydalis pseudobarbisepala, from the same source.

Hi Leena Wish you success, because a Lidén powerpoint picture shows the flowers of C. panda to be a striking blue. However, suggest the deeper soil in the pot should be fairly moist in summer, because Flora of China states 3900-4200, slopes, scree, so likely to benefit from its roots reaching slow-flowing snowmelt water. I'm currently trying to optimize growth for C. calcicola and a number of C. kokiana forms which definitely come from this type of environment. If you have snow cover in winter, perhaps no need to put the pot in the greenhouse.
I got C. pseudobarbisepala seed from a different Czech source, but this only grew one plant of a quite different species, possibly C. stricta. Some years ago I got a stock of C. barbisepala from Chen Yi (called trifoliata by her) and this increaes rapidly and flowers well in both pots and open garden.

I hope I find the right growing conditions for these beautiful plants (they seem more demanding), I'm very into all blue Corydalis right now. :). I planted C.cashmeriana last autumn, and it never came up this spring, which was a disappointment. I tried to make it a good place with a good drainage and lot of organic matter, and covered the ground with dry oak leaves for the winter to prevent the soil freezing deep.
I have grown successfully C.elata for many years, but it never produced seeds and last year I got some more of the same type of Corydalis, and I hope then they will now produce seeds. I have now 'Craigton Blue' (but I'm not sure if it is the right plant because in the pictures the flowers of 'Craigton Blue' look "meconopsis" blue, and my plant has just started to flower and the flowers are darker blue ???), C.elata 'Blue Summit' and C.elata x flexuosa 'Blue Dream'. BS and BD don't flower yet and also C.elata flowers here in July. All these seem to like it in woodland bed and increase by runners.
I have also Corydalis 'Korn's Purple' which started to flower two weeks ago, it is a young plant, and smaller than the elata-forms. I planted it behind the elatas, I should move it to the front of the bed.
-
What do you think, is this 'Craigton Blue'? Another possibility is 'Kingfisher', because the person who gave me this plant has also 'Kingfisher'. Or is this neither?
-
Hi Leena It's almost certainly one of the C. flexuosa x C. omeiana (or reciprocal) crosses (so not Kingfisher). At least five have been sold commercially in Britain (including Craigton Blue), but names used by nurseries have sometimes been confused, so can't always rely on the label. In addition the different crosses respond slightly differently to local conditions, so not always the same one which is the most vigorous in a particular place.. The stock in my garden which looks most like your picture was bought as Corydalis "Tory MP".

It does look a very different colour from 'Craigton Blue' and 'Kingfisher', which I find are more pure blue and yours is more purply, but I'm not sure if soil conditions could affect colour. Here's my 'Craigton Blue' for comparison, always a vigorous plant this time of year!
-
As Craigton Blue's "mother" I do not think that your plant is Craigton Blue, Leena. Diane's photos show the more dissected foliage of CB. CB can have quite a degree of red in the stem in early development, though that can fade out by the stage of growth that Diane's plant shows.
P.S. Diane's photo shows the colour of the flowers very well.
-
Thank you for the answers. :) Diane's plants color is the one I have seen in pictures online and right when my plant started to flower I thought that the flowers were the wrong color. Maggi, thank you for pointing out the difference in the foliage also.
And the real CB looks more floriferous, it wouldn't have been named if it wasn't good so I'll have to buy it.
I'll look up the how 'Tory MP' looks.
On the other hand it doesn't matter what the name of the plant is, but then again I would like to know what my plants are.. 8)
Except when I start to get seedlings, then they are ok. :)
-
Here is a photo from Colin Crosbie of Arisaema ciliatum and Corydalis 'Tory MP' in his garden. He mentions the sweet scent, which is also a feature of 'Craigton Blue' ( which has a strong honeyed scent) but the colour is a bit different and - of course(!!!) I like CB better! ;) ::) ;D
-
Thank you Maggi, for the photo. :)
-
Never thought I'd see the words "MP" and "sweet scent" in the same sentence!

Diane
Superb color on the Craigton Blue. Lovely.
Maggi
You might well , as 'mother', be allowed parental pride. A gorgeous plant.

Thank you, Geo - of course, as fathers often do, Ian claims all the glory - but in fact we are both simply caretakers as it was a Bumblebee who is the real star of the show!

Dear friends, what do you do, that your flexuosas stand upright so nicely?? My ones stand upright as long as there are no flowers. As soon as the first flowers open they start to bend and soon lie completely on the soil when not supported. They still flower nicely for quite long and then go immediately dormant without setting seeds (or very few only). Is it a matter of climate (too hot, I believe)??
The place in my garden is not too dark in my opinion - rather bright shade with occasional direct sunlight.
Or may be this is a matter of particular cross I have?? - though I have three different and they behave the same.
On the contrary - my C. ellipticarpa is still upright though long after flowering.
-
The unknown plant of which I posted the picture does stay upright without support (it could be more floriferous), but C.elata (if it is elata and not omeiensis) which flowers later needs support and it seems also C.elata 'Blue Summit' is going to need support (it doesn't flower yet). C. elata (or omeiensis) x flexuosa 'Blue Dream' is starting to flower now, I don't have any support for it yet, but I don't know how it will hold it's flower up.
Maybe some crosses don't need support and some do?? I'm also interested about other's experiences on this.
-
Craigton Blue is superb, I grow it in my own garden. It seems to be seeding around.
To me it smells of coconut.
Diane's photograph really has captured the wonderful colour.
-
I have looked at my Corydalis which I wrote about in the previous page. All of them flowered only once and the foliage of C.elata and C.elata 'Blue Summit' (no 1 and 4 in the picture) grew right on after flowering, but the foliage of other two (possible 'Tory MP, no 2, and C.flexuosa x C.elata 'Blue Dream', no 3) disappeared after flowering and only now some new shoots are showing. Is this typical of also other C.flexuosa-hybrids and 'Craigton Blue'
-
Leena
Yes most of these corydalis, including Craigton Blue lcan oose their foliage after flowering especially in warm dry weather of summer and new growth starts as the weather cools and moistens in autumn.
This growth pattern will vary according to the weather and the growing conditions - for instance some of our long established plants of Craigton Blue in the back garden lost their leaves some time ago and are now re growing while recently divided and replanted specimens in the front garden still have green flowers stems and the old foliage.
-
Thank you Ian. :) July was very hot here, August cooler and more rain and September has been very dry. I think the two which lost their foliage did it somewhere around end of July. Perhaps I should have watered them in July. Now it is too late here for new growth, there has been frosty nights but not yet winter at least for a month, hopefully longer.
My C.elata (or a plant I have gotten with that name) doesn't loose it's foliage at all, I was wondering as there is some confusion over C.elata and C.omeiensis if there is difference in this regard in those species? I grow this plant in two different places in the garden and it behaves the same way in both places.
-
Dear friends, what do you do, that your flexuosas stand upright so nicely?? My ones stand upright as long as there are no flowers. As soon as the first flowers open they start to bend and soon lie completely on the soil when not supported.
I had some very close to a net (on the side with less light) intended to keep various animals out. They climbed the net quite well. The only upright ones i have ever had
Happy new year
