Arum seeds

I agree, I clean the seeds while the pulp is still soft. The actual seeds
don't need to be cleaned or washed once the pulp is off. I've tried
drying the pulp, but for the two arisaema species I grow, the pulp sticks too
much to the seeds to be cleaned off once dried. I've also had no allergic
reactions to the pulp.
