description Passionflower Overview
Passiflora, commonly known as passion flowers or passion vines, is a large genus encompassing over 500 species of tendril-climbing vines, trees, and shrubs in the Passifloraceae family. Native primarily to the tropical and subtropical regions of the Americas, the genus is characterized by its intricate, symmetrical flowers featuring prominent coronas of colorful filaments. The floral structures were historically named by Spanish missionaries who interpreted their parts as religious symbols of the Crucifixion. Many species, such as Passiflora edulis, produce sizable fleshy fruits that are commercially grown for human consumption.
help Passionflower FAQ
Why is it called a passionflower?
Spanish Christian missionaries interpreted the flower's structures as symbols of Christ's Passion. The corona was associated with the crown of thorns, while other parts were linked to the nails and wounds of the Crucifixion.
Do all passionflowers produce edible passion fruit?
No. The commercial passion fruit usually comes from Passiflora edulis, while many ornamental Passiflora species produce bland, poor-quality, or potentially unsuitable fruit.
Which butterflies use passionflower as a host plant?
Several heliconiine butterflies lay eggs on Passiflora, including the Gulf fritillary and zebra longwing. The caterpillars can tolerate defensive chemicals in the leaves that discourage many other herbivores.
Can passionflower survive cold winters?
Cold tolerance depends strongly on the species. Passiflora incarnata, known as maypop, can survive winters in parts of the United States by dying back underground, while tropical Passiflora edulis needs much warmer conditions.
