I have no botany training and after coming up with this question many years ago, I am now finally daring to ask it
in public.I have noticed over the years that certain varieties of cut flowers keep flowering MUCH longer than other varieties in the same arrangement. I am thinking of alstromaeria, daisies, hypericum berries.Is there a known reason for this?a particular vascular system or stem makeup, place of origin?
I know this could be a "Why is There Air?" type question but I am secretly holding out hope for an answer.

Th much for your help/tolerance with this one!
best,
mindy

The answer(s) can be quite complex depending on how in depth you want to go, but, very generally speaking, genetic programming (genes, hormones, etc) is the key factor. Below is a link to the results of one study that will shed a little light on some of the factors. Much more can be found by googling 'flower senescence'.
