Pint plant Passiflora Kew Gardens. Elegant vine with 3-4″ pink flowers and white filaments. Very showy flowers on a medium-sized plant. Leathery leaves. An old-fashioned hybrid that has been around since the 1800’s, so the parentage is not known. Blooming year-round for us in a cool greenhouse with bright sun, its flowers are displayed best when staked or trellised. Easy to grow. Hardy to zones 9-11.
