One of my favourite pond plants and I find it hardy in my zone 8a garden. It seeds around (if there are rooting spots for the seedlings), though it shows no sign of becoming invasive, and the scented flowers are produced virtually non-stop. It flowers even when there are frosts. Very attractive leaves and unusual flowers.
The heights given are for water depth, as this plant doesn't go above the surface, other than just holding its flowers out of the water. I find it happiest in about 12"-18" of water, though it will still survive in a greater depth.

Has oblong green and red leaves that float on the water's surface. In the spring and fall, blooms rise out of the water bearing vanilla-scented, white flowers that are speckled with black.The long, oval shaped leaves float on the water, but it is usually the flowers standing up out of the water above the leaves, that attract attention. Bees are very attracted to the flowers and may be one of the main pollinators.
