Uses & Benefits
Winged-stem Passionflower brings genuine presence to the garden and earns its keep across the growing season. Winged-stem passionflower is a vigorous, evergreen climber of warm woodlands, bearing large, striking, purple-and-white flowers with complex central corona in the summer.

Passionflower is a well-evidenced calming herb: its flavonoid-rich leaf tea is official in European phytotherapy for nervous restlessness, with clinical studies on anxiety and sleep. The genus also gives the passionfruit, a vitamin-rich tropical treat.
Growing from Seed
Winged-stem Passionflower is one of those generous plants that come along well from seed. Broadcast the seed thinly over a fine, free-draining compost, sieve a little more compost on top, and water with a fine rose. The seed responds well to a cool, moist stratification period, which helps it break dormancy evenly. Pot the young plants on as they grow, harden them off gradually, and plant them into their final positions when sturdy.
Our Take
It grows as a vigorous, evergreen climber, so its place in the garden is easy to plan. Within its genus it stands out for garden reliability. Young plants want steady water; older plants take conditions as they come.
