Erythronium 2014

[Brian Ellis]

Thrives in the cool damp Scottish climate! 

It certainly does, a wonderful clump Steve.

Thanks for your notice, Dimitri. I have come to my computer only today, sorry.
It is quite surprise for me. Are there any more differences between those two except the yellowish tint ?

Zdenek, the difference is obvious just at first sight as for me  - please, compare yourself these erythroniums plants - E. sibiricum white form and caucasicum from W Transcaucasus. In two words, E. sibiricum is huge plant with big broad-petaled flowers, it has some white forms with not at all marked leaves with slightly bronze tint. Even now some white population of it in Altai are separated as a species - E. krylovii.
E. caucasicum is much dwarfer plant having elegant white flowers as a rule with narrow petals, rarely pinkish or yellowish. And Maggi is right it has very marked leaves, also to add it has white flowers with contrast reddish (not brownish!!) petal bases and stems.

Sorry, Dima - yes I  will admit that reddish is a  better description that brown!

[Oakwood]

Sorry, Dima - yes I  will admit that reddish is a  better description that brown!

Maggi  besides, your Ers different Craigton's cultivars vegetate quiet well at me in eastern Ukraine - I'm still waiting for soon bloom!!! many thanks for plants and for warm wishes about our terrible Ukraine...............

Erythronium hendersonii
Three different clones.
The palest clone (first two images) has a yellow halo around the blackcurrant centre of the flower which fades as the flower matures. The second clone is darker in flower (images 3 & 4). The darkest clone flowers significantly earlier than the other two and so often shows some frost damage in the flowers (image 5).
Unfortunately all are slow to clump up.

Following on from Ian's comments on particularly Erythronium revolutum in this weeks Bulb Log I thought I would post a few pictures here of todays visit to Knightshayes Court here in Devon.

Knightshayes is the place, of course,  where E revolutum 'Knightshayes Pink' was first selected and there are huge drifts of them in the wooded areas with some forms of a lighter pink.

[David Nicholson]

It doesn't take a lot of looking to find white revolutums (at least to my untrained eye they are possibly white revolutums)

[David Nicholson]

A Spring mixture; and to end one of only very few yellow Erythroniums at Knightshayes

[Maggi Young]

The wide expanses of revolutum are just breathtaking, David.
The white is not a revolutum- its a californicum hyybrid - white pollen and narrow filaments.

Beautiful - but not as glorious as the pinks, eh?

[Stephen Vella]

Nice Erythroniums everyone.

David that is amazing to see the mass displays of revolutum.

And Dimitri nice to see thoses wild ones.

Steve Garvie, nice to see thoses close ups of revolutum with dew hanging on them. Makes me wonder with all that damp weather that Erythroniums never suffer from botrytis?? Never seen botrytis here but we are very much dryer.

cheers
Stephen

Thanks Stephen, that's raindrops rather than dew. Also get a lot of wind here so I've never seen botrytis on plants in the open garden. I suppose it could be a problem in plants grown under glass protection.

[Stephen Vella]

Steve just noticed the hendersonii clones, i didn't know they come in such varied colours, we only have the mauve one here that I've noticed. I know of grower here that uses this for hybridising for those tall branching flower arrangement.
What's the origin of yours if you don't mind me asking? They are very nice.
Cheers
Stephen

Hi Stephen,
I procured these plants about 20 years ago and the labels have long been lost so I don't have exact details. One came from the late Kath Dryden (England) whilst another was from Ian Christie (Kirriemuir, Scotland), the third was from seed obtained from Ron Ratko (USA), only a handful germinated and all appeared quite similar (-the almost white plants pictured above with the fading yellow halo around the dark centre; the amount of yellow flare varies between individuals but otherwise they are very similar).
Cheers,
Steve

Steve, are you saying that the first of your photos (the light flowered E. hendersonii) is from Ron Ratko seed? It looks to me like it could be a hybrid with E. oregonum, with the yellow halo and slightly flattened filaments a result of the genetic influence of E. oregonum. There are a few places where the ranges of these two species meet and natural hybrids are found, so it could be that Ron was collecting from one of these areas...
