Passiflora aurantia

Passiflora aurantia or red passionflower is a profusely flowering variety with salmon colored flowers.

It is a moderately strong grower that does not climb very high.

It is not hardy but can be grown as a houseplant.


It is a tropical vine that clings with tendrils and grows up to 1-2 m high.

The leaves are three-lobed, dark green and measure up to 7 cm long. The lobes are not deeply cut and rounded. The leaf stalk is 1-3 cm long, usually has two glands and sometimes two stipules of 1 mm.

The flowers measure 4-8 cm in diameter and do not fully open. When they open, they are cream colored. Over a period of several days, the color darkens to a beautiful salmon pink and finally dark red.

The fruits are green, ovate and measure up to 5 cm in diameter. They are light purple at maturity, with grayish flesh and numerous black seeds. The flesh is edible but not particularly tasty.
