Helleborus multifidus is always the first one to start flowering, though I'm not sure if this is species or a hybrid, because it has never set seeds.
It is deciduous, like H.multifidus should be.

My H. multifidus usually have the flower stems and remarkably different main foliage appearing at the same time. I usually get a few seeds but the flower stems succumb to fungus easily.

It is unusual to have flowering and new growth occurring at the same time, botrytis is the usual fungus infection I see, regular spraying with a systemic fungicide as the flowering bracts are appearing can reduce the intensity of the infection. Growing environment, damp and poor air circulation are conducive conditions for botrytis. Some species and many hybridus are more prone to infection.

I agree with Jeffnz that spraying a systemic fungicide is best; but Captan is much less expensive and often as effective.

I think H.multifidus which picture I showed earlier might be a hybrid, but this H.multifidus should be right, because it was grown from wild collected seeds.
This one sets seeds (unless frost damages them).
What Jeff wrote about botrytis made me wonder if these are now too dense, but they grow well and never had any trouble. Knock on wood!

We do not have snow cover over winter, winter is cold and very wet, these conditions are ideal for botrytis.
Your green multifidus is the species, the earlier one has to be a hybrid that may involve the true species, never the less a good hellebore with outward facing flowers.

Thanks Jeff. :)
I like also the hybrid, and the flowers are good outward facing. It's leaves also die in the autumn, like in the green multifidus, but unfortunately it seems to be sterile.
It was grown from Swedish seed ex seeds.

Unusual that it is sterile, does this apply to both open and hand pollinated flowers? I have only come across a few hybridus that are sterile, my plants of Betty

They both look great Leena. The first one which may be a hybrid, resemble a bit my H. purpurascens, which also is the first one to flower here, erupting from the ground just the same.
The foliage follows much later and I actually like it that way.

Few Helleborus flowers, with a particular plant from ex. H. 'Cherry Blossoms' that is very nice.

713316-1

H. purpurascens, already done by now.
713318-2

This one from a very robust specimen obtained from seeds; 5 years old looking like 10 :)

I don't know how it would be if hand-pollinated, but open pollinated it doesn't set seeds.

The first one which may be a hybrid, resemble a bit my H. purpurascens, which also is the first one to flower here, erupting from the ground just the same.

Thanks Gabriela, the colour and the size of flowers is similar to H.purpurascens, but the shape is not, at least not now. The plants I have grown from your seeds flowered the first time this spring and they were early, though they also grow in an early spot. :)

Yes, the flowers are different, just the behaviour is the same :) The garden location makes such a big difference in early spring. The ones who receive more sun can flower with more than 1 week in advance than another one I have on the side of the house, which remains shaded.

I like the anemone, especially the yellow tips to the extended nectaries. Unfortunately this is not retained if the anemone is crossed with a similar coloured double.

It is raining today, so here are some Helleborus pictures, new flowers this year. Many old (and new) ones still suffer from winter 2022, but it was nice to see new flowers. :)
The first ones are from seeds I got from Jeff.
The names are from what the crosses were.
The last pictures are from a really nice yellow which flowered now for the third time, and it survived the bad winter, so it is one more plus for it.
My favourite.

These two were sister seedlings, and I especially like the white one, it looks  sideways nicely.
The last one is also one of my favourites though flowers are quite small.
