Passiflora caerulea, the blue passionflower,bluecrown passionflower or common passion flower, is a species of flowering plant native to South America (Argentina, Chile, Paraguay, Uruguay and Brazil). It is a vigorous, deciduous or semi-evergreen tendril vine growing to 10m (33ft) or more, with palmate leaves and fragrant, blue-white flowers with a prominent fringe of coronal filaments in bands of blue, white, and brown. The ovoid orange fruit, growing to 6cm (2in), is edible but bland.
This popular and showy plant has attracted a number of common names. In Paraguay it is widely known as mburucuy in Guaran. Other names include blue crown, flower of five wounds, southern beauty, wild apricot, Jesus flower. The specific epithet caerulea means "blue" and refers to the blue coronal filaments. In Japan, it's called - ( Clock plant ) due to having 12 petals, a central stamens and stigmas resembling a timepieces's winding mechanism, and curly green tendrils resembling wound springs.
Passiflora caerulea is a woody vine capable of growing to 15-20m high where supporting trees are available. The leaves are alternate, palmately five-lobed like a spread hand (sometimes three or seven lobes), 10-18cm long and wide. The base of each leaf has a flagellate-twining tendril 5-10cm long, which twines around supporting vegetation to hold the plant up.
The flower is complex, about 10cm in diameter, with the five sepals and petals similar in appearance, whitish in colour, surmounted by a corona of blue or violet filaments, then five greenish-yellow stamens and three purple stigmas. The fruit is an oval orange-yellow berry 6cm long by 4cm in diameter, containing numerous seeds; it is eaten, and the seeds spread by mammals and birds. It is edible to humans, but bland in flavour. In tropical climates, it will flower all year round.
Passiflora caerulea is widely cultivated as a wall-climber or as groundcover. In milder temperate areas it can be grown outside, and can become invasive, the twining shoots constantly appearing unless eradicated. It has gained the Royal Horticultural Society's Award of Garden Merit.
A number of cultivars have been produced from the species:-
The species has been used in numerous hybrids.
Though the fruit is edible, it is rather insipid when eaten raw. It can substitute for blackberries. A tea can be made of the flower which is said to alleviate stress and anxiety. However, tetraphyllin B and epi-tetraphyllin B, cyanogenic glycosides (which liberate hydrogen cyanide when activated by enzymes), have been found in the leaves. It is possible to boil away most of the cyanide.
The flower of the passion fruit is the national flower of Paraguay. The intricate structure of the flower has generated Christian symbolism, each part representing a different part of the Passion of Christ. See Passiflora "Etymology and names" section for more information about the symbolism.
