Passion Flowers

Type of Flowers
Passion:
Passion ( Passiflora ) flowers is a genus of about 500 species of flowering plants, the namesakes of the family Passifloraceae. This Flower Meaning Holy Love,Faith and BelieveThey are mostly vines, with some being shrubs, and a few species being herbaceous. For information about the fruit of the passiflora plant, see passionfruit. The monotypic genus Hollrungia seems to be inseparable from Passiflora, but further study is needed.






The family Passifloraceae has a pantropical distribution. Passiflora itself is absent from Africa, where many other members of the family Passifloraceae occur (e.g. the more plesiomorphic Adenia). 
Nine species of Passiflora are native to the USA, found from Ohio to the north, west to California and south to the Florida Keys. Most other species are found in South America, Eastern Asia, and Southern Asia, New Guinea, four or more species in Australia and a single endemic species in New Zealand. New species continue to be identified: for example, P. pardifolia and P. xishuangbannaensis have only been known to the scientific community since 2006 and 2005, respectively. 
Some species of Passiflora have been naturalised beyond their native ranges. For example, Blue Passion Flower (P. caerulea) now grows wild in Spain.[1] The purple passionfruit (P. edulis) and its yellow relative flavicarpa have been introduced in many tropical regions as commercial crops.






The passion flowers have a unique structure, which in most cases requires a large bee to effectively pollinate. In the American tropics, wooden beams are mounted very near passionfruit plantings to encourage carpenter bees to nest. The size and structure of flowers of other Passiflora species is optimized for pollination by hummingbirds (especially hermits like Phaethornis), bumble bees, wasps or bats, while yet others are self-pollinating. The Sword-billed Hummingbird (Ensifera ensifera) with its immensely elongated bill has co-evolved with certain passion flowers, such as P. mixta. Yellow Passion Flower (P. lutea) pollen is apparently the only pollen eaten by the unusual bee Anthemurgus passiflorae. However, these bees simply collect the pollen, but do not pollinate the flowers. 
The leaves are used as food plants by the larva of a number of lepidoptera. To prevent the butterflies from laying too many eggs on any single plant, some passion flowers bear small colored nubs which resemble the butterflies' eggs and seem to fool them into believing that more eggs have already been deposited on a plant than actually is the case. Also, many Passiflora species produce sweet nutrient-rich liquid from glands on their leaf stems. These fluids attract ants which will kill and eat many pests that they happen to find feeding on the passion flowers.
