I believe seed of the Pacific Slope erythroniums is viable for a long time, as long as it's stored under reasonable conditions. However, these species generally only germinate after experiencing *significant* winter chilling. A sowing in November or December may be too late, delaying germination until the second spring following. If you have dry seed on hand, don't sow it now; wait until mid-summer. Then put the pots or flats where the winter weather can chill them. -- Rodger Whitlock Victoria, British Columbia, Canada Maritime Zone 8, a cool Mediterranean climate on beautiful Vancouver Island
