Colchicum autumnale seeds will usually germinate in 30-365 days, even under good conditions germination may be erratic. Sow seeds about 13mm deep in a Peaty seed sowing mix at about 15°C.
Outdoor Treatment, in temperate regions, can give seeds exactly the sequence of cold and damp and warm conditions needed to encourage germination. Check your weather conditions to see whether they may be appropriate. Shady sheltered conditions are recommended (to keep humidity and temperature regular) in a free draining, but water retentive medium - this can be in pots in a cold frame, where they can be easily protected from weeds and animals.
