The taste is top when you grow them yourself
Passionfruit Grafted Black is a vigorous climbing perennial with deep green leaves and fragrant purple and white flowers. Fruit matured to a deep purple/black in colour and contains sweet, edible pulp.
Black passionfruit is widely adapted but requires a rich, well-drained soil and support – in the form of a trellis, pergola, arbour or fence, ideally about 2 m high. Passionfruit requires full sun to fruit reliably, although it tolerates occasional mild frosts.
