Nymphaea odorata subsp. tuberosa (Paine) Wiersema & Hellq.

Rhizomes often constricted at branch joints to form detachable tubers. Leaves: petiole green with brown-purple stripes, stout. Leaf blade abaxially green or faintly purple. Flowers: petals white, rarely pink, elliptic to oblanceolate, outer usually with broadly rounded apex. Seeds mostly 2.8-4.5 mm.

It is a temperate plant. It grows in ponds and quiet water. It suits hardiness zones 3-9.

The young unrolling leaves and unopened flowerbuds can be boiled for 5-10 min. and served with butter. The seeds can be fried like popcorn or parched and the winnowed kernels ground into flour. The rootstock produces brown tubers that can be cleaned and boiled. They are bitter.

Can be grown by seedlings.
