Passiflora gracilis

Passiflora gracilis

Passiflora gracilis or Crinkled Passion Flower is the only annual Passiflora.

The plant grows exceedingly fast and flowering is very abundant and followed by a profusion of red orange berries.

This Passiflora is less frequently cultivated, probably because it has to be sown every year, but its exuberant growth, abundant flowering and fruiting make it a very nice species to grow.

Description:

Passiflora gracilis is a perennial vine with tendrils of 2-2.5 m long.

The leaves are three-lobed, 2.5-10 cm long and 2.5-13 cm broad, on a petiole of 2.5-9.5 cm.

The flowers are 2-3 cm in diameter. The bract is 1.5 cm, pubescent. The sepals are white and sometimes greenish white, 1 cm long and 0.4 cm wide. There are no petals. The corona consists of two rows of filaments. The outer row of filaments is white with purple stripes, 0.6-0.9 cm long. The inner row of filaments is greenish, 0.1-0.3 cm in length.

Flowering occurs from mid spring to mid fall.

The fruit is a berry red to orange-red when ripe. The seeds are 0.4 cm long and 0.2-0.3 cm in width.
