Capparis spinosa subsp. nummularia

"Wild passionfruit" redirects here. For the true wild passionfruits, see Passiflora.

Wild passionfruit, or (locally) "caperbush" is an Australian native plant. It is a subspecies of the caper.

Its name in the Arrernte language of Central Australia is Merne arrutnenge.

Wild passionfruit is a tasty bush tucker food. When it ripens, the skin goes orange, splits open and the little black seeds become visible. It is then ready to eat. The seeds are hot and spicy when crushed. It grows prolifically in riverbanks in the desert.
