Passiflora actinia

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.
