Chris; Beautiful plants

 Today there were flowers in 2 of my white Eranthis. Already last year I discovered they were different. Pinnatifida has dark leaves and larger flowers and is reddish in the middle of the flower. The other one I bought as Sibateranthis and I know that it is a synonym name for pinnatifida. Its leaves are narrow and bright green and it is not reddish in the middle of the flower. Are they both pinnatifida and is there so much diffrent between the plants of pinnatifida?

Not one of the Eranthis bought at last years Gala has a flower. I'm quite angry just now. Probably just like snowdrops they don't like being moved while growing. I bought Grunling, Schylters Orange, semi plena,  Noel Ayres and Lady _ _ _ _.

A nearby churchyard has quite a large population of Eranthis hyemalis.  It wasn't hard to find some with extra petals, as in the photo.  I found several like this.  Is this normal?

Mark stay calm - you are absolutely correct they do not take kindly to having their roots damaged when they are in full growth. No matter how careful you are damage will occur which will mean the the plant cannot grow on well and the bulb will end up smaller than it started out the season.
Left alone and with good growth they should flower next year.

Alan I always find some of our plants with extra petals it is usually just a seasonal aberration as I have marked plants to check them the next season.

Mine are in a good mix with lots of leaf mould so fingers crossed for next year.

Alan your plant may be stable because all the floweres are the same

On the other hand, I decided I would try to split one of my Eranthis hyemalis specials last year.  So mid March I dug it up, washed all the soil off the roots, chopped the tuber in half with a sharp knife and painted the cut ends with a horticultural sealant.  Both halves are now just coming into flower.  So that was some pretty rough treatment and the Eranthis seems none the worse.

Mark...they will flower next year, just don't disturb them. The Lady_ _ _ _ is probably 'Lady lamortagne'

If anybody here has received in the last years seeds from my Eranthis so please read this :

Karl - Shibateranthis isn't species name but genus name. Difference between Eranthis and Shibateranthis you can easy see growing them from seeds. Representatives of Genus Eranthis has two seedleave from seed - Eranthis hyemalis, cilicica.
Shibateranthis has one seedleaf from seed - Shibaneranthis longistipitata, sibirica, stellata, pinnatifida...

You can see the difference on attached pictures

Karl, the second one looks like Eranthis(Shibateranthis) byunsanensis, which according to some taxonomists is the same as E. pinnatifida, according to others it's the same as E. stellata and according to some other others it's a seperate species with one subsp. E. byunsanensis grows in the wild in Korea, while E. pinnatifida is Japanese. If I remember correctly Tatsuo posted some pics of this species on the forum last year!

I think the most distinctive feature of 'so-called' E. byunsanensis is its true petal (nectary) shape and colour. Other white Eranthis (Shibateranthis) species have more bifid and yellowish tipped nectaries. I'm hoping taxonomists settle this down shortly.

The 3 flowers on left side are E. byunsanensis and right are E. pinnatifida. (Sorry, this pic is larger than usual!)

[WimB]

I should have noticed that, thanks Tatsuo! Karl's plants are both E. pinnatifida, the second one has more greenish nectaries. E. byunsanensis has funnel-shaped nectaries, while E. pinnatifida has bifid nectaries...I  think that is the key difference.

As for the taxonomy, according to genetic research, there is a difference between E. pinnatifida and E. byunsanensis: http://link.springer.com/article/10.1007%2Fs12374-011-9201-8?LI=true
E. pungdoensis, which is often described as E. byunsanensis var. pungdoensis shows no genetic difference with E. byunsanensis.

What an interesting discussion! Thank you alltogether for sharing these informations!

I have an additional question concerning this complex. How is Megaleranthis saniculifolia ranged
in the complex. Is it closely related to Eranthis and is this species in cultivation?
