It's pretty clear from the behavior of a lot of my arisaema tuberettes
that cold dormancy isn't required for all individuals of all species. A
lot of the seeds started last winter and spring went dormant by early
summer and have since reemerged and are growing again, having received no
treatment other than benign neglect in the hoophouse. If I get energetic,
I might check to see which species are doing it most vigorously, but I
know that one that I was surprised to see (since it normally gets plenty
of winter chilling) is an A. triphyllum selection from Roy Herold (his
`Green Giant'). Interestingly, none of the other triphyllums did this.
I wonder if this behavior is confined to juveniles?
