The story
Oyster nut is a giant East African gourd vine whose flat seeds have been eaten by Chagga, Kikuyu and Swahili households for centuries, roasted or boiled and often given to nursing mothers; it climbs trees and lives for years.
Planting
Full sun, rich soil, heat, humidity, and a big tree or strong trellis; plant seed in the wet tropics. Male and female vines, so plant several.
Growing
Water through dry spells; it needs its support strong, since the gourds weigh 30 pounds.
Harvest and use
Gourds ripen in a year or so; split for the flat seeds, which are dried, shelled and roasted.
What to watch for
Cold, and inadequate support.
