My helleborus hybridus seedlings are kept in a frostfree greenhouse and mostly their growth is impressive. About 30% flowered the first year (thanks to an article of Jan Sijbe on the site www.heleborus.be).

The new growth on some of the seedlings however is disturbing. The leaves are small and shiny and they seem to grow less good than most of the other plants.

Does anyone know what this can be?

I am loosing about 5 plants a day like this and I don't like it at all!!
