"OK but what keeps them dormant? They cannot have jet lag forever. Someth=ing
makes them start growing. It cannot be moisture and it cannot be "dead
reckoning". What could be the advantage of starting late in the natural
conditions?"
Day length can also be an important factor for many plants &
animals in temperate climes. I don't know whether or not it is for
some Arisaemias  perhaps someone here does know? Other factors may
also come into play.

Robin Bell Ithaca, NY, zone 5, where the candidissimum are
decidedly late.
