Taking its botanical name from a translation of Latin, Passiflora is the type genus for its family, the Passifloraceae. Comprising 500-odd species of mainly evergreen tendril-climbing vines, the genus also includes a few shrubby species. Commonly known as passionflowers, they mostly come from tropical America, though the range does extend to Asia and the Pacific Islands. Grown mainly for their beautiful flowers and subsequent pulpy fruit, passionflowers are vigorous growers that clamber and cover surfaces quickly. Fruits of many species are mildly to quite poisonous, though others are edible and quite delicious. Many parts of the flower are regarded as symbolic of the crucifixion of Christ. |
