Most arisaema seeds do not need a cold period. What they get from a winte=r in
the wild is the removal of some substance on the seed surface that inhibi=ts
germination. That winter washing can easily be duplicated by an overnight
soaking in a glass of water with a few drops of detergent added.

If they are then kept in a moist paper towel in a warm area (the method
originated by Marge Edgren and popularized by Norman Deno), they will usu=ally begin
germinating within a week or two, but then you have to decide what to do =with
them.

I plant them in a pot, indoors under lights, and grow them on until they =grow
dormant. I then collect the tuberlets and refrigerate them in slightly mo=ist
conditions (usually in a plasitic bag with almost dry sphagnum) for 3 mon=ths.
They can then be planted again either in a pot or in a bed (depending on =the
weather) and start their second period of active growth.

The point of all this is to shorten the time frame to flowering size.
