das habe ich heute ergänzend in Denos aufzeichnungen gefunden...in englisch aber leicht verständlich:

Sowing in open ground is the method used for Eranthis hyemalis. The seeds ripen in early May and are sown immediately as they do not tolerate dry storage. The seeds receive the requisite three months at 70°F during the summer and the requisite fifty-five days around 40°F during the fall. They germinate during late fall, winter, and early spring. Growth is completed during the cool and cold days of spring. The seedlings are programmed to grow at temperatures around 40°F. If the temperature rises to 70°F for any length of time, the seedlings cease growth. If they have not had time to build up a tuber, they perish. Since it is troublesome to provide bright sunlight at 40°F indoors, the sowing in open ground is the easiest and simplest method for growing Eranthis from seed.

interessant auch die temperaturabhängigkeiten der sämlinge, da kann man auch nochmal was falsch machen, vor allem bei überwinterung der aussaat im kalten gewächshaus, wenn es trotz kalter außentemparaturen bei sonnigem wetter im Gh schnelll mal in richtung 20°C/70°F gehen kann.
