Passiflora actinia or Passion Flower is a vigorous Passiflora with pleasantly scented flowers.
Contrary to other Passiflora, it does better in a bigger pot.
Flowers and bears fruit only in the tropics or in a heated greenhouse, not when grown as a house plant or in the garden in temperate climate.
Fruit will mainly be produced through cross pollination. Fruit from self pollination is very small.
Flowering occurs from September to December in its habitat, from February to April in the northern hemisphere. For the rest of the year, flowering is minimal.
Passiflora actinia is a vine with smooth, subterete, slender and wiry stems, up to 10 m long.
The petiole is 1.5-3 cm long with 4 and sometimes 6 glands. The leaves are entire, oval, 3-11 cm long and 2-8 cm wide, membranous, with smooth edges and green.
The peduncle is 1.5-3.5 cm long. Flowers are white and violet, 6-8 cm in diameter, single and pendulous. The petals and sepals are white or greenish white, the corona is white and purple striped. The flowers open only in sunny weather.
The fruit is ovoid to spherical, 2.5-4 cm long and 2-3 cm wide, yellow when ripe and edible.
