How

Well, Victorias waterlilies flower and develop seed in one season. In the
fall, the plant dies from the cold. But because seed was produced, one
starts
a new plant the next spring.<

WOW! They do their thing in a hurry! I guess their pools dry out in
nature??

Most people think of Victorias as annuals but actually they are quite
capable of being perennials. But they are exceedingly demanding in their
light and water temperature requirements so that up here in the temperate
regions we treat them as annuals. V. amazonica is the more demanding of warm
water temperatures but has a more stable environment and probably is a
perennial in habitat. But, I have been told that V. cruziana (which may be
capable of surviving as a perennial) in nature comes from further south and
evidently goes through a cool season and is functionally an annual. Here at
the Brooklyn Botanic Garden in our Aquatic House we overwintered our
Victoria Longwood Hybrid this past year. It certainly regressed
significantly but came back quickly as the days lengthened and light
intensity increased. This not an aroid issue but thought it might be of
interest.
