Edible Uses

Edible Parts: Leaves  Root  Seed  Seedpod  Shoots
Edible Uses:

Fruit[105, 161]. Another report says that the plant has an edible seedpod[213]. The reports for edible fruit probably mean the seedpod[K]. Seed - cooked[257]. They can be used in soups or can be ground into a powder and then used as a gravy[257]. Root - cooked. Too small to be a staple food, but useful in an emergency, the roots taste best in late autumn, winter and early spring[213]. Leaves and young shoots - cooked[213].
