Nymphaea in subgenus Anecphya come from seasonally dry pools in Australia. They are magnificent plants with enormous fragrant flowers. They are not well known because they need water much warmer than would occur without supplemental heat in ponds in most of North American and Europe, even in summer, and they are huge plants. They grow fine in cultivation without drying out seasonally, but they are adapted for this, forming large tubers. My 6' x 12' / 182cm x 364cm pond is perhaps big enough for one, and my summer water temperature is even higher than they require, but I've just never gotten around to finding one. Leo Martin Zone 9?
