RE: Fern Life Cycle Rates

Germination seems to be very fast (s. Hoshizaki) when the sporocarps become flooded. The production of sporocarps start after they get dry feet again. How fast the intermittent development could be I wouldn't know (so far, I've been more succesful in letting them pine away than growing them) but I reason that if they can't survive the dry season as rhizome they ought to be able to start producing sporocarps within a few months.
