Passiflora has a largely neo-tropic distribution. The vast majority of Passiflora are found in Mexico, Central and South America, Jamaica and parts of Cuba.

This perennial vine is quite showy when in bloom; it will send tendrils to climb onto a trellis or tree. As it is a host plant for butterflies, it will periodically be eaten by young caterpillars, but it grows new leaves soon after.
Horticulture potential: This lovely vine would beautify an archway or pergola. It is easy to grow with very little care and no diseases are associated with this plant.
