Thank you from me, also. I just received exciting (for me) Eranthis seed from SRGC seed exchange, I hope I get some seeds to germinate. :)

Leena, there is still hope :) Two years ago I had successful germination of Eranthis hyemalis Aurantica from the SRGC seed exchange. I achieved about 50% germination the first year and I didn't soak the seeds. The pots were placed in an unprotected outdoor seed frame where they got lots of rain.

From Robert: I'm somewhat vexed that when I offer, and label as such, a true breeding line, that the seed is not label as such in the seed list. It is very different from open pollinated non-isolated seed.   
I can well understand such frustration, Robert. I think that  perhaps the seed reception managers  can have trouble in determining when such provenance is reliable so  prefer to take a wider "lumping " approach.  :-X

Wim, thank you for boosting interest in Eranthis with your excellent IRG article.

Right now I have Eranthis hyemalis and pinnatifida in flower.
Last year I replanted pinnatifida in lattice pots in the garden, to be able to bring them in the green house to get a better pollination. Until now they have been planted directly in the garden. They flower well there but have only set seed one time in about 5 years.

 That's a good point , Poul - there is often a good reason to have such plants under cover in certain climates - not merely for survival but, as you say, to get better pollination and seed set.

Viz a viz hellebores; many in circulation now are from micropropagation, e.g. 'Anna's Red'. Where they are from seed then they shouldn't have a cultivar name. I like the Ashwood approach who sell their Helleborus x hybridus as Ashwood Garden Hybrids - no single quotation marks, hence not a cultivar name.

A general question :

Is Eranthis hyemalis self fertil ?

Thanks
Hans

Hans,

My guess is that E. hyemalis is self fertile. They do not appear to be apomixis. If some clones come 100% true from seed, without apomixis, then they must be self fertile and a lot of inbreeding has gone on.

Many thanks Robert ,

I have a similar idea ...
Now I'm testing this theory ...in my greenhouse is a E.hyemalis ( isolated ) and I pollinate it every day ...we will see !

Best wishes

Don't you think we all get carried away by "name/taxon collecting"? I'm seriously thinking about removing all the name tags from plants in my garden. So a rather nice snowdrop will just be "Snowdrop" and a rather nice Hellebore with pink spotting will be just that and maybe next to another that just happens to be  yellow. Save a fortune on labels and stress as a result of blackbirds chucking labels about.

Anyhow, some Eranthis come 100% true from seed (like Schwefelglanz', 'Hafod' and 'Moonlight')

So what happens if you cross, say, 'Hafod' with 'Moonlight'?  I guess the seed parent could always beat the pollen parent or is it that these Eranthis are much more likely to be self-fertile than to be pollinated by a different variety, which is what makes them likely to come true. 
Almost in Scotland.

I soaked the seeds overnight, now the pots are inside in warm and I thought to take the pots outside after about a month. The temperatures in March are still freezing here most of the time, but I can cover the pots with snow and also many seeds like fluctuating temperatures, sometimes below freezing and sometimes warmer. I'm prepared to save the pots for another year. :)

You have a point, but personally I am fascinated by taxonomy (yes, I'm weird)! Take as look at this which I got from Tom Mitchell Tweet: http://t.co/CNayt5UVqv

But they would say that wouldn't they, vested interests strike again. No reason why the rest of us should put ourselves on the breadline buying more and more labels.

More guess work on my part....

Most Ranunculaceae are out breeders. Many, such as Aquilegia, will also accept their own pollen. With too much inbreeding it is a good idea to keep a look out for inbreeding depression, detrimental and lethal recessives, that sort of stuff.

When working with out breeders and making fertile x fertile crosses (i.e. an uncontrolled cross) I often get a mixture of selfs and out crossings. I see this all the time with Rhododendrons.

What goes on with Eranthis, I don't know, but I will be having fun finding out myself.

I've been on both ends of the seed exchange system; donor and distribution. Maybe I don't like rules in my world but I do have a few:
1.) Be kind - near the top of the list!
2.) Have gratitude.

I'm thankful for all the seed I receive and I'm thankful for all the hard work that does into a seed exchange to make it work.

I've received some interest seed, such as the lepidote rhododendron seed that turn out to be some sort of a elepidote rhododendron. There have been many other unexpected surprises.

I like the saying of the Joy of Painting guy Bob Ross - "There are no mistakes only happy accidents".

With this in mind, I sow my seed, go the bed, and get a good night sleep.

Some say Bob Ross was a painter, maybe he was a Bodhisattva. :)
