Answer 2

They bloom when the nights are longer.

My reasoning is the mention of PHOTOPERIODISM. Photoperiodism means the reaction to length of a day or night cycle, since fall is the beginning of shorter days and longer nights, it is only reasonable that the answer is that THey bloom when the nights are longer.
