David, that's a great success story - your Primula allionii cutting obviously loves tufa!  I have never grown plants in tufa and wonder how different the conditions are to growing amongst rocks?
Title: Re: Primula 2010
Post by: David Sellars on February 10, 2010, 08:07:45 PM
Robin:

You are right.  Plants in tufa grow differently compared with plants amongst rocks.  The main difference is that they grow much more slowly so they retain a compact habit if you like that kind of thing.  I certainly do.  So you need lots of patience both watching them grow and also planting in tufa as the technique is quite exacting and takes time. The good news is that you can fit lots of plants into one tufa block so it is a great space saver.

One observation that I have not seen in the literature, is that plants in tufa flower more readily than in regular rock garden soil.  My theory is that they are a little more stressed which brings on flowering.  I have very small Kabschia Saxes that I planted last year that have already flowered this year.

Of course you can really only grow lime-loving or lime tolerant plants in tufa. I like to choose plants that have a natural habitat on vertical limestone rock such as Primula allionii and Saxifraga longifolia. I have found it best to have tufa beds mostly north facing as they could have a tendency to dry out in the summer. Plants that grow on vertical rock also tend to like north facing slopes so that works out well.

If you have the patience (and the tufa), try it.  If you love alpine plants you will love tufa!

Now there's a challenge.....but no idea if tufa is available here....there are limestone outcrops in the region and locally we're on granite but i would love to grow lime-loving alpines if I can.  Thanks for your detailed information David  :)

David, lovely little plant.  I wish I could grow allionii outside, but I am afraid the climate is too harsh.  When I have a larger supply I will try your method in tufa.

Marianne:

I could not keep the species Primula allionii alive in our climate until I tried tufa.  Allionii hybrids have been OK though in regular rock garden soil. 

I think if you can replicate the natural habitat (to the extent possible) you have a better chance.  They do seem to prefer growing in a vertical limestone face.  I have a winter rain shelter over that part of the tufa garden which may also help.

I wish I could grow allionii outside, but I am afraid the climate is too harsh.  

I wonder if it is not cold-hardiness that is the limiting factor there, but conditions (e.g. winter wet, as may have been alluded to in David's comments), since P. allionii cultivars (I don't have the "straight species") grow outdoors here in regular soil in this cold but dry climate?  (On the other hand, perhaps mine are P. allionii hybrids and thus I am seeing some hybrid vigour?)
Title: Re: Primula 2010
Post by: Maggi Young on February 11, 2010, 10:57:57 AM
I believe that it is winter wet which is a problem ....and here, in Aberdeen, the next problem is summer wet!  These plants just don't enjoy sitting about in the rain.... who could blame them/  :P

Primula kisoana is an "easy doer", although can flag when too dry (which it often does in my dryish garden).  I try to hit it with water in the summer, to keep the fuzzy foliage looking its best.
Title: Re: Primula 2010
Post by: Lori S. on February 13, 2010, 10:51:12 PM
From Rick Lupp's website for Mt. Tahoma Nursery:
"Primula "Pink Ice" is a vigorous hybrid of P.allionii x p.pubscens "Harlow Carr". This is the perfect choice for the grower who wants the perfection of form and beauty of P.allionii without all the difficulties. This plant is compact, strong growing and buried under a bloom of large, crystalline pink flowers for several weeks in spring. Not to be confused with the P.allionii cultivar "Pink Ice"."

Huh, now I'm thoroughly confused.
Any guesses on which this is then?  (In other words, is it P. 'Pink Ice', or is it P. 'Pink Ice'??   ;D)

Although we have a lot of snow the mice have awaked last Friday and then they have eaten 3000 Primulas incl. the roots over night!! All Show Aurikulas - 500 plants, 500 Primula allionii and nearly all of my new young Alpine Primulas - 2000 plants and more than 100 different Androsace. So the work of the last 10 years was destroyed while some hours. Only the larger plants in my green houses have survived. They has eaten all Lilium seeds and all seeds of Daphnes, too, although the soil is frozen.

The one that dies is the true allionii.

That's like the method used to distinguish Cyclamen africanum and C. hederifolium: leave them outside during the winter. The ones that freeze to death are (were) C. africanum.

Speaking of P. allioni: I grow all my auriculoid primulas in pumice and they seem to like the conditions. I keep them under cover at all times and water by immersing the pots. So far, so good. Come back in five years for a more definitive report.

In the open garden, the only primulas doing their thing here are the old double mauve-pink 'Quaker's Bonnet' and pale butter yellow Primula vulgaris, the ordinary primrose of English hedgerows and banks. It is a surprisingly difficult plant to acquire! If any member lives near a wild stand of P. vulgaris, they would be doing the world a favor to gather seed for the exchanges. Gardens need simple, calm plants as well as high-strung, nervous ones.

Didn't E. A. Bowles refer to mice in the garden as vampires where crocuses were concerned? Seems like their destructive tastes are even wider than perhaps commonly realized.

A good friend on Saltspring Island has endless trouble with mice and rats eating seeds and seedlings of all sorts of things in his greenhouse, though his new cat appears to have taken care of the rat population.

hi, not sure if Marianne answered about the first allionii in these pages. It looks like "Anna Griffith".

A few from me, hopefully in the right order, "Malcolm", "Rosemary" "William Earle" and "Jan". The last one seems very slow here but a really good deep colour.

I wonder whatever happened to "Crowsley's Var". It used to be the most common of the three varities mentioned in books from the late 50s/60s. I have Apple Blossom and Viscountess Byng (that one I've kept losing) but no sign of Crowsley.



Title: Re: Primula 2010

It's good to be posting back though I have been enjoying many of the pictures of the irises, Cyclamen and Narcissus here on and off.

I find I rarely lose them. Even if the tops rot off (yay! cutting material) most varieties they come from the base again. It happened to virtually all of them when they spent the winter with my father and he decided to put up bubble wrap, 4 months in a warm moist giant plastic bag.

Can I ask where you got the crowsley from (assuming it was a commercial sourse)?

Title: Re: Primula 2010

Here are some "white" allioniis

"Eureka" which is supposed to be one of the best pure whites.

"Avalanche" which was regarded as one of the best in the 70s when it was being sold by Joe Elliott. My first one had a touch of pink and he replaced it. I always regard it as cream. Often there is a touch of pink in it.

"Lacewing" picotee. Not sure I really like it.

"Crystal" opens pure white and then goes pink. Rather fetching.

"Kermis" old pic. I noticed this one hasn't flowered for the last few years, I have no idea why that it.

Hi to you all! I know that I'm not very present, but I don't have such beautiful plants as yours. I like very much to see and read your comments.

Yesterday I went in the woods and there were millions of P. vulgaris , a yellow carpet.

But, I found this (sorry, I cannot manage to insert photos as clickable thumbnails   :-[):

Title: Re: Primula 2010
Post by: Maggi Young on March 22, 2010, 11:49:20 AM
Well, strictly speaking, since the pink primula is not in the exact geographivcal range of P. sibthorpii, it is not that... though if the plant were being cultivated one would certainly give it that name..... the natural range os sibthorpii is Northern and  central Greece,the Crimea, Turkey, the Caucasus and Armenia (this from John Richards' book) ..... given that you found it in your local woods it must simply be an unusual colour break.... which is, after all, how the sibthorpii will have arisien in the first place.... ;)


Here are Maddi's pictures of both magnificent yellow vulgaris and a lovely pale form,  for those unable to download her photobucket images....

Post by: Mad on March 22, 2010, 12:45:10 PM
Thanks Maggi! In fact I consulted too the Richards' book too and I was not sure of the identification because of the area. But... there were no other ID possible... Especially after seeing the photo on Primulaworld site.  :P ;D

I will check better that zone, maybe I'll find some other forms.

I'm happy that you like the others two. Even if they are common, I think they are breathtaking when all in flower in the woods.

Mice are a menace and I am very sorry for you.
In the time I grew auricula primulas I sometimes had mice eating the rhizome. I then found that there is a small chanse that root fragments left in the soil will act as root cuttings. So please do not throw it all away oo early. Some cultivars may recover even if decreased to small stumps of roots.
Perhaps you already know this.

The first few Primulas of my season. I had been thinking that they were late this year but I see from my records that some I'm posting now were later last year by just a few days. Maybe my cultivation has not been as good as last year as the plants I won prizes with at the South West AGS Show last year (28 March 2009) will need at least another week (or two) to get to the same condition as last year and the Show in on Saturday. Oh well, can't win 'em all!!

P. 'Wharfedale Superb'
P. 'Lindum Heavenly'
P. 'Lindum Moonlight'

hi, as Maggi says, the second plant looks more like "Mary Berry". The other one, not sure, it does look nice though. Maybe it's another named clone but the labels got mixed at the nursery?

I sowed seed from my Mary Berry, I think all were fairly dark though. I just label them as P.allionii, I passed some on but I kept a couple. I'll probably put up some pics over the weekend.

Axel,
You obtained a fine plant from these roots. Indeed a rare and attractive species.

It is told that they are completely hardy here. I suggest they need a cool place and please take care that they never get too dry.
For pollination at first have a look into the flowers. Primula have thrum-eyed and pin-eyed flowers (in German: kurz- und langgriffelige Blüten). Take a small brush and give the pollen of a thrum-eyed flower to a pin-eyed one (or vice versa).

Thank you Gerd. They were kept in a greenhous at first. When I got them two weeks ago, I put them in this box with sphagnum. They liked it. Before they were kept more dry than I did, because there was some rotting material at the outer part.
They are very narrow I could not see whether they are thrum-eyed or pin-eyed. In some flowers there were quite a lot of pollen so I just kept going from one flower to another. I hope it helped.

Axel,
Please 'google' for thrum- and pin eyed primulas (pictures) and you'll easily note the difference.
Otherwise to pollinate like the way you described can't be wrong. I was told that at least the primula hybrids are not aware of the fertilisation rule.

I am *very* interested in primula, and starting a brand new garden after a move. The only species that fit into the moving truck were the allioni, marginata and auricula. I am trying to start the remainder of the former collection again from seed.

As I also have no greenhouse or other proper growing space on my new property, some 100+ species of primula seedlings are presently perched here there and everywhere in the house, awaiting spring, so I can work with them better somewhere outdoors, once I construct a proper potting bench in a corner.

As I will still have a year to think about it, considering the stage of the seedlings, I would appreciate some ideas/input from those of you who grow large collections of the genus IN THE OPEN GARDEN.

Obviously the alpine sorts can find homes in the rock garden and many can go into a woodland setting.
Now that I no longer have naturally moist/wet areas as I did in Ontario, I am contemplating the species that would like consistent moisure at their roots. I am also thinking about some the challenging Asian species and where I might be able to keep them happy.

I realize this is a very open-ended, general question with such a large genus---but I am trying to find some unique ideas (back in Ontario I was at the start of building a "fernery" to house some of the difficult to grow in the garden ferns, grew some specific primula in troughs with specialized growing material etc). I am thinking about some of the "Cypripedium areas" that others have built, or digging in a moisture-retentive barrier....etc. etc.

The only given is that the collection has to be open-grown.

Who has seen some interesting solutions? Or has solved some primula cultivation problems in a unique way, so that a number of species requiring similar conditions can be grown together????

A few more P.allionii, hopefully is this order.

P.a "Mary Berry"

P.a. 81-19-3

P.a. Malcolm

P.a "Austin"

and finally a seedling I raised, though it might be a hybrid. It always reminds me of a slightly faded fabric but I still like it.

Re: Primula allionii 'Mary Berry' thanks to Maggi, John and Mark for feedback. If John's plant is "right" then neither of my two plants are correct nor is Marks. I had a bit of a Google to see if I could come up with anything else and pinched this from Jim Almond's Web Site (hope he doesn't mind).

Lots of delightful Primula pics over the last few days folks.

I though Primula addicts might like to see the following couple of images I took from the South West AGS Show last Saturday. Dave Philbey, who in his growing career, stretching back many years, has probably forgotten more about Primulas then most of us will ever learn mounted a display of some of his breeding work.

The Primulas in the Alpine house are now at their best.
I got the x miniera Riesenblüte from the Stopp nursery and
it is truly a giant flower!
In our meadow garden P.vulgaris starts to spread all over the
meadow, we began with a few plants from Zigana Pass from
North Eastern Turkey about 20 years ago.They also crossed
themself with the other P.vulgaris.

Post by: Rodger Whitlock on April 02, 2010, 06:36:24 PM
At our local club's show last week, I acquired a small offset of Primula × pruhoniciana 'Schneeweiss' aka 'Snow White', one of the Ahrends hybrids.  The exhibitor was kind enough to give me one of the crowns at the end of the show, which makes three of these cultivars now in my possession (with the proviso that I have to take the names on faith).

This incident led to our other primula enthusiasts mentioning that at one time she had 'Schneekissen' and may still have it. If she can find it and there's enough to share, that would make a fourth of the Ahrends 'Schnee' cultivars to come into my hands.

This are excellent little primulas. They are nearly as dwarf as their parent Primula juliae, with the same tendency to creep about by rather thick underground rhizomes. As far as I know, their flowers are all white or near-white. The ones I have are all a pale ivory color, which I greatly prefer to a dead bone white.

As has been mentioned in these forums before, I've had 'Schneesturm' (Snowstorm) and 'Schneetreiben' (Snowdrift) in the garden for many years. Snowstorm has performed very well and gradually spread into a mat that is, as I write, covered in flowers. Snowdrift, planted in the same area, never did well, barely hanging on to life. It seems to be a weaker plant than Snowstorm in all respects. I've moved some of Snowdrift to a location where other hybrids of P. juliae do well, and potted some up, but neither of these treatments has invigorated the plant. Possibly it's become badly virused with age and thereby weakened. According to Smith, Burrow, and Lowe's Primulas of Europe and America, Ahrends was working on his hybrids of P. juliae as early as 1913, so these are now very old cultivars

The only cultivar names I've found for members of this specific group are:

    * Schneekissen (Snow Cushion)
    * Schneereisin (Snow Journey or Snow Travel)
    * Schneetreiben (Snowdrift)
    * Schneewittchen (Snow Witch?)
    * Schneesturm (Snowstorm)
    * Schneeweiss (Snow White)


Does anyone know of other members of this small group of cultivars?

Also, who is growing these, and where are they available commercially? Google and the Plant Finder reveal that Schneekissen is available in the UK, and Schneesturm in Germany, but what about the rest? As a group, they are nearly out of cultivation, perhaps having weakened fatally with age. It would be a shame for these charming plants to utterly disappear.

Lovely to see primulas again, and there have been so many super plants on the Show threads.

This one is way out of season because it is in the southern hemisphere. It is one of two seedlings I gave to a nursery friend. Mine are about the same size but not in bud, probably not until OUR spring. It is the soldanelloid Primula wollastonii.

[attachthumb=1]
Now I look at it, it's a really awful picture. I should have focused on the flower instead of mid stem. Louise might send me a better one when it's fully out. She gave me P. primulina in exchange. :)

P. vulgaris var. pulchella...more whitish compared to P.vulgaris. I've no record if this 'var. pulchella' is correct. Any comments?
P. veris...likes calcareous soil and dryish, sunny place
P. elatior...grows in shadow in moist loamy soil
P. elatior hybrids...likely hybrids with P.vulgaris or P.veris, showing larger flat flowers
P. auricula...still in bud stage; beautiful and absolutely hardy.
P. x pubescens 'Blue Wave'...a phantastic color, still small plant. I love it! A special thank you to the generously donator ;) ;D

Robin,
yes 'Blue Wave' has a fascinating deep blue- extraordinary contrast.
In the Swiss there are now many places with masses of P. vulgaris (in meadows) and P.elatior (in forests).
Their flowers perform magic yellow carpets with marvelous displays.
Have you found and seen some already?

Post by: Lesley Cox on April 11, 2010, 12:25:10 AM
Chris, I don't know that you have to do anything except make sure it is cool and shaded at all times, damp compost. It won't like direct sun or drying out at all. JUst a matter of waiting I think until it's ready to flower. If it died down over this last winter and is through again, it may well flower or begin to make a bud down in the rosette, very soon. It is after all spring flowering, not autumn and the one on Louise's plant is an aberration but very welcome of course. Keep it free of green fly too as they tend to distort the foliage and may allow virus in.

P. wollastonii has a very pleasant trait in that when it is planted out and one lightly weeds around it, any root that is hit and slightly damaged, may send up a new, little rosette of growth. I grew it in the early 80s in a cool, shaded raised bed and had little lines of rosettes from where I'd weeded around it. If one were to trim off whole roots they should make successful root cuttings.

Hi Lesley,

Wow, if I had to courage to just plant it in the garden.... right now its being totally cossetted!  Here it is, looking very healthy.  Yes, the foliage died right off last autumn and now its nose has sprouted with this lovely foliage.  I got it from John Richards and the name has a question mark after it, so if it flowers I'll send a pic to him to see if it really is what it says on the packet.

Chris, having enlarged your picture, your foliage looks much hairier, like our Teddy's fur compared with that of a smooth Jack Russell. Perhaps this is just natural variation? Of the 30-odd seedlings I had to start with (lost some now) all were the smoother kind, though with a soft, velvet pelt.

I purchased seeds too and they germinated readily. I planned to plant them in a trough in the ground with waterreservoir. What about wet from this reservoir in winter? Do I have to protect them from the wet winterconditions from above? Some glass?

Two picture just snapped, one with P. kisoana in front of Jeffersonia dubia (I think I like the look of Jeffersonia just as much in foliage as in flower).  The second shot shows more kisoana, and some shoots: Arisaem sikokianum, Cypripedium reginae.

So many primula species happily flowering in the open garden here---I think this genus will really like the cooler, moister weather of Nova Scotia. I have never had such prolific and long bloom compared with the open and gone bloom I used to get in Ontario.

Primula auriculas sitting pretty.

Also can someone help with identifiying this species originally grown from wild seed from the Alps????

As I've said in the Bearded Iris thread life is hectic in the Nicholson household at the moment with little time for gardening and for catching up with the Forum. I missed the flowering of most of my Primula allioniis and marginatas this year but here are a few of the later flowering x pubescens and one little marginata that Luc kindly sent to me, thanks Luc.

Primula x pubescens 'Yellow Form' a little past it's best.
A little x pubescens seedling sown in December 2007-worth giving a name too?
Primula marginata 'Jack Drake'

..... and a few more.

Primula x pubescens 'Apple Blossom', a bit tatty round the edges.
Primula x pubescens 'Blue Wave' now fairly widely distributed and more to go out when flowering is over.
Another x pubescens seedling, this one sown in June 2007.

Two interesting Primulas I bought recently.
First - Primula 'Kusum Krishna'.  I thought at first glance, Primula sonchifolia but the leaves are different and unusual.  The label says, a new hybrid raised in Scotland, but does not give the raiser or parentage.  Does anybody know any more ?

The second I bought from Kevock Nursery's stand at the Perth SRGC Show.  It was labelled 'Blairside Yellow'  but may be a seedling.  Flower shape, colour and leaf are all different (but I like it).

Ps.  Maggi, we seem to have two early Primula threads.

Thanks for the nice comments Armin.  I'll change the name on my Mrs Hearn, David - Love that yellow form of P. x pubescens.  I have the pink one.

Think I'm going to put some of my marginatas in the garden.  They seem to love the gravel and sandy soil, and even though I lose the farina, they bloom better.

Just invested in 6 more show auriculas after buying the latest book about them, so next year should be even better.

Chris,
primulas can be a real passion. They are so variable in color and forms.

P. veris is one of the local wild primulas naturilizing very well in my meadow and surrounding raised beds. Seedlings appear now everywhere and many 'escapers' please my neighbours with their tiny flowers for the time being.

 This primula has been raised by Graeme and Hilary Butler of Rumbling Bridge Nursery, Roma.
They describe Primula x ‘Kusum Krishna’ as a deep blue, white eyed Auricula."Our best hybrid yet, received a P.C. in 2007. Large, stunning deep, blue flrs. Stemless habit."

I love all the primulas, but especially the wild ones growing by the side of the roads.  And your P. veris (we call them cowslips for some reason - does anyone know why?) are so lovely.  I grow a red one which I've had to curtail or it would have populated my entire garden!  It comes up in the paving cracks and everywhere.  It was labelled Coronation Cowslip when I got it, but I've no idea why.  Its a deep blood red colour.  I'll try taking a photo tomorrow - weather permitting!

This red P. veris strain I have now for some years out of the garden of the late Mr. Kellenberg. I was passing by his garden while driving to work. Many times I admired red primulas on the opposite side of the road.
One time I took a heart and stopped. A neighbour told me that the original Gardener had died the year before and the Primulas were planted by him.
Since I had only a few of the yellow type in my garden it was easy to dig them out and give them to friends.
Since then I only have this red type. For some years I dug out every lighter shade, but this year I let them bloom.
From light orange down to nearly black. But true yellow will still be dug out 8)

No problem with sending you seeds Robin, I just mark the darkest this year and you will get enough to have lots for selection. This year they are on average lighter than last year. The plants which flowered last year red and darker which were my darkest last year (and the year before)are now from dark red to even orange (this I would have abjected). There are some a wee bit darker from these old plants (which nearly died last summer for lack of water) and are smaller  than their offspring from last year. Some shown here.
I will try some pictures tomorrow if it stops wetting (rain would be boasting).

These ones you won`t get seeds from. This year very late I cut all too yellow types for a bouquet.
One flower of glow I left. It will be sown separate.  So from the motherline you will only get true reds, Robin.
Still raining here, just a bit all day so no picture from outside.
I will be in Swiz at the Vierwaldstätter lake from the 16 th to 26th of may. Gersau is the city I will do some sculpturing (Dragonia). If you could make it there I could even dig out some Primulas for you.
I have also some friends in Schwyz where I could leave some for you if you think it fitting for you. Otherwise I will send you only seeds ;).

Hi Robin,

 I do but only to keep the winter wet off it, so a frame might do just as well. It dies back to a tiny resting crown in the winter and I just put it in a tray under glass so I can water it occasionally from below to keep the compost moist but the crown dry. Once growth starts I repot it into fresh compost then move it outside into a shady plunge with my cypripediums etc. This also raises it up to nearer nose height!

On last Friday 2 members of the SRGC, Sid and Brian, visited me and wanted to take pics of Primula clusiana in the wild. Sid will write a Primula book. So we went to the best location of Primula clusiana in the Alps which I know, and this location is at the mountain behind my house (garden). All were so surprised because we saw so many different forms of flowers what is never seen by other Primulas. So it is nearly impossible to identify Primula clusiana if you have not seen the leaves,...
The colours of the flowers are not correct, it should be blood-red, my camera is not the best.
Now I will show you some Primula clusiana and other plants.
Then we went to a location of Cypripedium calceolus (near my house, too) where Sid and Brian took many pics. They were so happy to see such wonderful Cyps in the wild. I will show some pics under "Cypripedium calceolus".
I hope my pics are of interest for you.

It grows in a crack in pretty dry soil, and has nice pink flowers:

Aha, the ol' missing "i" trick.  Diane, I find the USDA links incredibly useful for North America flora, even having info pages on invasives that exist here.  At the bottom of each USDA Plant profile page, there is typically an ITIS link (Integrated Taxonomic Information System) for that species, useful to find out what the latest taxonomic standing is, as sometimes the USDA is slower on the uptake.  There is also typically a link to CalPhotos, with a good selection of photos, many in situ, although for P. rusbyi, only one photo.  And the last thing I check, is to see what the genus-species standing is in the new online Flora of North America... sometimes there's a link on the USDA page for it, sometimes not.  As an example, you can check by googling Flora of North America Primula to get to the Primula classification IF IT HAS BEEN WRITTEN YET, large parts of FONA are still not published.  For issues of synonymy, the FONA often gives some good insight:

excerpt on P. rusbyiSome individuals from the Sandia Mountains of New Mexico have a shorter corolla tube more or less equal to the calyx; these plants have been described as P. ellisiae. A single population can include individuals of both types, and the difference probably represents only a developmental stage of the flowers or minor morphological variation in some localized populations; preliminary genetic analyses (S. Kelso and P. Beardsley, unpubl.) reveal no substantive genetic distinction between these individuals and those from elsewhere in the range

I have grown both "species", find then amenable in clutivation (this was years ago), and glad to see some consolidation as I agree they are not sufficiently distinct.  Wish they'd do the same for little red-and-yellow Aquilegia species in Western USA, as it seems every slight different characteristic has resulted in a new "species", yielding dozens of lookalikes. ::)

The USDA site is extremely helpful, and I actually find it more up to date than most sites.  For examply, it's now quite a few years ago that North American asters changed to Symphyotrichum and other genera, but the RHS database has not yet caught up.  Maybe the UK taxonomists didn't agree, but they did actually print the changes in the RHS Garden magazine, they just never changed their database.     

Every year when I am checking the names on the AGS seedlist database (just started). I download the whole USDA database as I find it is the most up to date, easily accessible resource for N American plants (and, as Mark says, some invasives)
http://plants.usda.gov/dl_all.html (http://plants.usda.gov/dl_all.html)  Warning - it's too big a file to be practically maneagable for searching - so I download it in alphabetical chunks.  I also use the list to create my own list of cross references as they are now listed the wrong way round for me with the old names alphabetically in the order of their new names (they used to do it the other way, with the "old" names listed alphabetically which is more useful for my needs, often easier just to scroll down an alphabetical list then use a search)

Agreed, CalPhotos is a brilliant resource, I use it a lot.

Thanks Diane, interesting to learn how you are using these resources.

How do you handle areas where the North American Flora and those outside of North America don't necessarily agree, specifically where there is not universal agreement and adoption of Dodecatheon and Douglasia as being Primula & Androsace.  One thing I like about the Flora of North America treatments, is that they spend a lot of time summarizing the genus, particularly on controversial ones.  On Douglasia, the 2nd paragraph makes a strong detailed argument for Douglasia as a valid genus, as the body of current evidence and science is, as of yet, inconclusive. It states: "This treatment follows the current, conventional view in North America of a segregate generic status for Douglasia".  So, does the RHS follow the FONA decision to maintain Douglasia as a separate genus?

Similarly with Dodecatheon, but here they took a "have it both ways, while sitting on the fence" approach, stating: "These observations have resulted in the transfer of all species of Dodecatheon to Primula (A. R. Mast and J. L. Reveal 2007). For those wishing to adopt this concept, the appropriate names are provided here in synonymy".

Anyone know what this is? Received as P. bella, but that doesn't look right...

A lovely hybrid between Primula vialii and P. flacida occurring in a bed of Vaillii. Not sure if there is a name for this particular hybrid, I know it is a fairly common occurrence. Picture alongside one of its parents.
Susan

This is a lovely plant Susan - I was wondering if it has the same wonderful scent as flaccida?  Given that both parents tend to be pretty much biennials with us I won't ask if it is any longer-lived! We currently have neither. Not too bothered about vialii but I'd like to grow flaccida again.
