Most probably factors related to their habitat are of influence like
the absence/presence of the right poliinators, the timing of the
monsoon in the area where a specific species grows or the altitude, and
subsequent later time the temps are right for growth (although that is
not a factor for candidissimum as it comes from reasonably low
altitudes). Many species keep the internal clock they had in the wild
even if they are cultivated. Of several species I have clones that
consistently break dormancy early and even keeping them at 2 C won't
slow down their progress, it is simply intrinsic for that particular
clone or species whereas other clones of the same species break
dormancy much later. The growth pattern of some species can be changed
and of some not. Apparently candidissimum is one that resists change.
