Passion Flower (Passiflora caerulea) is a striking tendril climber grown for its complex, exotic flowers: white petals topped with a crown of blue-and-purple filaments around a prominent central structure. Native to South America, it grows well in warmer parts of India on trellises, fences and arches, climbing readily with its curling tendrils and lobed green leaves. It flowers through the warm season and may set edible (though bland) orange fruits. Tolerant and vigorous, it prefers full sun to light shade with well-drained soil. A favourite for pollinators and a host plant for some butterflies, it benefits from pruning to control its enthusiastic growth.

Growing tips
In India it does best where summers are not scorching, including cooler hill stations and the milder months on the plains; give it a tendril support and prune in spring to keep it vigorous and floriferous.
