Notes and assumptions
- Grown in a pond: rhizome or tuber in a basket of heavy loam at the stated depth; needs full sun and still water.
- Tolerates cooler water than V. amazonica, with a taller rim, so it is the one grown outdoors in summer pools of temperate gardens (as at Longwood).
- Grown as an annual from seed in temperate gardens.
