However, just about every aspect of a plant is determined by it's genetics.
A species is simply a group of individuals which are capable of reproducing
offspring which resemble the parent group. There are exceptions and
'errors' can creep up in DNA, if there is a seed which has a mutant
character(such as temperature preference, which may be controlled by more
than one gene) and it grows in an enviroment to which the mutant is suited
then the mutant will florish.
Wouldn't it be great for the temperate growers if N. truncata could grow
well at highland temps, or maybe a lowland N. villosa for us lowland
growers?
Just my opinion,
