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.
