Passiflora caerulea — blue passion flower
Passiflora caerulea is the botanical name for the blue passion flower, the hardiest and most exotic-looking climber you can raise from seed. It is the species behind our passion flower and passiflora range within the flower seed collection.
History & origin
Native to South America, the passion flower was named by early Spanish missionaries who saw in its extraordinary structure the symbols of the Passion of Christ — the corona as the crown of thorns, the stamens and styles as the wounds and nails.
The names capture both halves of the story: Passiflora means “passion flower,” from that religious symbolism, while caerulea means “sky-blue,” for the colour of the filaments crowning each bloom.
Botanical characteristics
A vigorous, tendril-climbing woody perennial, Passiflora caerulea bears intricate flowers with white petals and a striking corona banded in blue, purple and white, often followed by egg-shaped orange fruits. Fast and self-clinging, it is a spectacular choice among our climbing flowers, and the nectar-laden blooms draw in bees as one of our pollinator-friendly flowers.
Growing Passiflora caerulea from seed
Passion flower seed germinates slowly and erratically, so be patient — sow in warmth in spring, and soaking the seed beforehand can help. Grow young plants on under cover, then plant out after frost in full sun against a warm, sheltered wall with a sturdy support. Our flower growing guide and flower sowing calendar cover the timing.
