My first one of the season-Lewisia tweedyi- seed grown a number of years ago and I know Lesley had some.
-
Looking great David !
I should have some to show here too in a week or so !
-
Thanks Luc.
-
I do indeed David. A couple haven't flowered yet but 6 are the same as yours above and the remaining 2 have flowered pure white! This pleases me as the two commercial whites I have and I assume are seed raised, have given me no seed at all. Both yours have seed starting.
I also had half a dozen seeds on the two plants I bought at the Trillium weekend in October, of tweedyi 'Ashford Yellow.' 1 seed up so far.
-
Lewisia tweedyi 'Rosea'
-
Gorgeous, David. Such a luscious colour, it looks almost edible. 8)
-
Very nice David. Just as well I have the few seeds of the yellow as the two plants have recently died I see. My fault, they became overgrown. >:(
-
Thanks folks.
-
One of my favourites David ! :)
This is Lewisia tweedyi - lemon form - in full flower, but it suffered from rain and even hail over the last weeks...
-
Superb images of Lewisia tweedyi – I am not able to grow this plant.
-
I like the lemon form. My 'Ashford Yellow' (now deceased) was slightly less lemon and closer to a goldy shade. Well worth growing from different sources.
Franz, I don't believe you. ;D
-
Very nice Luc. I'm hoping to pay a visit to Ashwood Nursery in the next few weeks and have a shopping list longer than my arm with a Yellow tweedyi in top spot.
-
My Lewisia are probably a little later than some as they have to wait in their winter quarters, under covered shelving outdoors, until there is room to bring them into the greenhouse. Lewisia pygmaea is the smallest I have and even looks lost in a 3" pot, still very pretty though.
-
The first cotyledon of my season.
-
Always a treat David !!
Here are some of my colour variations.
-
Here's a common one (rescued from B & Q for 50 cent!)
It was planted outside last autumn in one of the troughs and seems to have sailed through one of our wettest winters. Never covered or anything.

Nice show Luc.
Well done Kevin.
-
Can't complain about that Kevin. Luc, your rich red is a stunner. :)
-
Health warning!!!!!! Lewisia is a highly addictive genus ;D
-
When you see 'em like that it's easy to know why!
Very tidy glasshouse, Martin..... if you're trying to make us feel guilty, it won't work... .we're too far gone.... :P
-

Why do you think it's a long shot and not very high definition, the crap is just out of sight in the foreground and the mess on the far bench is suitably out of focus. Who says the camera never lies ;)

;D ;D ;D ;D ;D ;D

And you've got it badly Martin. ;D Is there a Lewisias Anonymous group? David N probably needs to think about that too. :)
-

I think there is such a group, Lesley... quite a few old LAGS about....... ;)
-
Watch it!, Maggi. :P ;D
Actually I have just got the cure, I have only about 15 Lewisias left in the greenhouse and a few in the garden. :P
-

Totally amazing show Martin !! :o :o :o F a n t a s t i c !

::) ;)
Is it a cure though, Michael... or simply a remission?
-
Definitely a cure Maggi. Anyone got a cure for Daphne or Hepatica addiction? :)
-
All I can say Michael is that Lewisias are probably a cheaper addiction!
-
What the heck Martin, this whole Country is broke anyway so I might as well join the club, at least I will have something nice to look at and the Government is unlikely to take them from me , but then the way things are going here at the moment you would never know. :P
-
Nice pictures and plants anyone, thanks !
Here Lewesia rediviva is flowering now . One of my favourites , maybe the best flowers of all . But on the other hand we get a very short period of joy with this one ....
-
Nice rediviva Kris. They are several weeks from flowering here.
-
Here is one of B&Q's cheepos - it cost me 5p last October !!. Not bad flowering for that price.
-
Yes, a pretty good 5p's worth Tom. ;D
-
My lewisias this week.
-
These ones are almost getting wild in the garden, striving without care and having survived the -20°C of last winter as well as the +40°C and extreme drought of last summer - not bad a reward for a few seeds dropped there.
[attachimg=1]
Do you know how long is it usually blooming ?
-
You should get 2-3 weeks but shorter if temperatures soar. If you deadhead you'll probably get a second flush in late June.
-
thanks Martinr.
do you know if self-sows and spreads easily in a garden ?
-
Croquin, it depends............If it is a fertile clone it should set seed.They germinate quite freely in the sand plunge of my Alpine House. They do not survive winter outdoors here very easily as it is usually too wet and they rot off at the neck. Some will grow outdoors here in the right position but I've given up trying for the moment. You may do better than me if you have fairly reliable snow cover. It might be worth collecting some of the seed and growing under glass until you find out if they will self sow in your garden.
-
thanks for sharing Martin.
I'll collect some of the seeds and leave the others.
I suppose that you have to sow them as soon as they ripe, is it coorect ?
-
You can sow them straight away or keep them and sow early winter
-
OK Martin, I'll sow ASAP, so that plants have grown a bit before winter and can eventually bloom next spring.
Or, as I fear, is it the kind of plant that has patient seeds requiring exposure to cold, waiting until spring to germinate ?
If it is seasonal germination, nothing.
But if it is germinating after cold stratification, maybe I can manage something ?
What would you say ?
-
I would sow when ripe and leave exposed to the cold (but not too wet) through winter in a cold frame or something else which will stop them being very wet, I doubt they will germinate this year but you never know!
-
I'm having my worst Lewisia season ever with only one cotyledon flowered so far. The only thing I have done differently this year is to grow in plastic pots rather than in clays-ah well!
One that doesn't seem to have been affected-Lewisia columbiana var. rupicola
-
David, you're not alone. Most Lewisia growers I've met at shows this year have been grumbling.
-
David, I found that Lewisias grow better in plastic pots so it must be environmental or some other reason, probably the mild winter. Mine used to flower better after getting some frost.
-
Thanks Martin and Michael. My Lewisias, to some extent, get very badly treated. They get chucked out of the greenhouse at the beginning of September into covered shelving outside, to let the bulbs come back in and they come back into the greenhouse normally in May when enough space is available for half-dormant bulbs to replace them in the shelving. Maybe my watering regime in plastic pots has been too "robust". Time will tell but it wouldn't surprise me if they are in full flower in September.
-
Some of mine, flowering over the last couple of weeks.
Flowering has been ok in pots, but less abundant on the plants in the open garden...
Last picture is my Lewisia Alley... ;D
-
Very nice Luc. You're obviously not having flowering problems this year!
-
Luc,
a perfect show.
-
Now if only this rediviva hybrid had done this last week for the Tewkesbury show :'(
-
That was a sorry miss, Martin. It is a cracker though.... and at least we can admire it here. ;)
-
Very nice Martin. My Lewisias have been a dead loss this year.
-
Stunning plant, Martin. Congratulations.
-
Found this interesting coloured Lewisia cotyledon among many others last week
in a garden center.
-
Very nice Rudi.
-
Found this interesting coloured Lewisia cotyledon among many others last week in a garden center.
could be a hybrid with L columbiana which could result in that colour
-
Thank you Diane and David,
I think, that you are right Diane. I was also a bit in doubt of the unusual
flower shape, not quite corresponding to L. cotyledon.
-
This is my Lewisia 'Constant Comment'
Blooms in May and sometimes in September again.
Said to be hardy in zone 6 but is hardy here in my zone 5
-
Very pretty Arie and a one I haven't seen before. I just checked the RHS Plant Finder and only one supplier lists it on this side of the pond.
-
'Constant Comment' is very fine. Very floriferous and nice and compact on short stems. I like it a lot.
-
Are these Lewisia colour forms grown from seed strains or micro-propagated?
I have some Lewisia tweedyi with odd flowers now, and they were only sown in February from Nargs "yellow form" seed. They are just a pale yellow so far, with some slight orange/pink, so guess they don't come true.
-
Plants of Lewisia tweedyi as 'Ashford Yellow' were offered at the NZ Trillium Group weekend last year and I bought two. As I remember all those on offer were in bloom with consistently yellow flowers. Not a rich, golden type of yellow but definitely yellow, all the same as I recall. I had just 5 seeds from my two plants and all are up, small, unflowered plants as yet.
I thought I had lost the two originals as the foliage got a bit overgrown by other things and rotted but just last week I found both are growing away strongly from the centres.
I also bought a good yellow cotyledon form a couple of weeks ago at our OAGG Show. The colour is the same as that of the tweedyi plants.
