Passion fruit

Passiflora edulis

A vigorous, evergreen, tendril-climbing vine from the subtropics of southern Brazil, Paraguay, and northern Argentina, grown both for its strikingly intricate purple-and-white flowers and for its edible passion fruit. The flower is a small work of engineering: a ring of white-and-purple petals beneath a fringed corona of wavy purple-banded filaments, with the five anthers and three stigmas held on a raised central column at exactly the height a large carpenter bee brushes as it forages. Where winters are frost-free (USDA zones 9b-11b) it is a fast, hard-climbing perennial that can blanket a sturdy trellis or fence in a single season and produces round, leathery purple or yellow fruits whose aromatic, seedy pulp is the fragrant passion fruit of juices and desserts. Two honest cautions matter: it is a frost-tender plant grown as an annual or under glass where colder, and the unripe fruit and the foliage contain cyanogenic compounds and are mildly toxic, so only fully ripe fruit should be eaten.

Care tips

•

Give it a strong support: a sturdy trellis, arbor, fence, or heavy wire - a mature passion-fruit vine is heavy and vigorous, and a flimsy structure will fail under it.

•

Treat frost as the hard limit: in zones colder than 9b grow it as a warm-season annual or in a large container moved under glass for winter, and don't expect it to survive a hard freeze outdoors.

•

Eat only fully ripe fruit (usually after it drops and the rind wrinkles); the unripe green fruit and the leaves contain mildly toxic cyanogenic compounds and should not be eaten.

Lifecycle

Planting

Where hardy (USDA zones 9b-11b), plant in spring in full sun in rich, free-draining soil against a sturdy trellis, arbor, fence, or wire - the support must be strong, because a mature vine is heavy and vigorous. Give it consistent moisture but never waterlogged roots. Everywhere colder it is grown as a frost-tender annual, in a large container moved under glass for winter, or in a greenhouse, since frost damages or kills it.

Transplanting

Set out young plants or rooted cuttings in warm weather once frost has passed, and disturb the roots as little as possible; like many vigorous vines it sulks if moved roughly. Plant it where it can stay, since an established vine is large, heavy, and awkward to relocate, and guide its tendrils onto the support from the start.

Early growth

Young vines grow fast in warmth, full sun, and steady moisture; water and feed regularly through establishment and tie or train the questing stems onto their support before they tangle into neighbors. Watch for the same speed becoming a problem - pinch and guide early so the vine builds a framework on the trellis rather than a smothering mass.

Maturity

A mature vine flowers and fruits heavily in frost-free climates, climbing 15 to 30 feet and needing yearly pruning to remove old, crowded, or unproductive wood and to keep fruiting on vigorous new growth. Fruit ripens to deep purple or yellow and is usually let to drop, then gathered; individual vines are relatively short-lived and decline after a few productive years, so plan to replace them.

Propagation

Grown from seed (which can vary, especially for hybrids) or, to keep a good fruiting selection true, from softwood cuttings or by grafting onto vigorous rootstocks. Cuttings of named or reliable selections are the usual route for a dependable fruit crop, since seedlings are variable.

Pollination

Needs cross-pollination

Like its relatives, the large fringed flower is built for big bees: the anthers and three stigmas are held on a raised central column at the height a large carpenter bee (Xylocopa) contacts as it forages, so those bees are the effective pollinators while smaller insects take nectar but pollinate little. Many passion-fruit selections are partly or wholly self-incompatible and set fruit best with cross-pollination between genetically different plants, which is why commercial plantings rely on bees and, in still or pollinator-poor sites, on hand-pollination to ensure a good crop.

Larval host

Butterfly

Gulf fritillary (Agraulis vanillae)

Gulf fritillary caterpillars are obligate Passiflora feeders, and passion-fruit vine (Passiflora edulis), like other passionflowers, can serve as a larval host where their ranges overlap in warm climates.

Specialist

Butterfly

Gulf fritillary (Agraulis vanillae)

Agraulis vanillae caterpillars are passionflower specialists dependent on the genus Passiflora, which includes this species; the family-level host dependence is well established for passionflowers generally.

Pollinates

Bee

Eastern carpenter bee (Xylocopa virginica)

The flower's anthers and stigmas sit on a raised central column at large-carpenter-bee height, the same structure that makes carpenter bees (Xylocopa) the effective pollinators of passionflowers; on this neotropical species the documented carpenter-bee pollinators are large Xylocopa, with the eastern carpenter bee a plausible visitor where their ranges meet.

For people

Edible

Grown as a fruit crop: the fully ripe purple or yellow passion fruit has aromatic, seedy pulp eaten fresh or used in juices, sauces, and desserts, and is the source of the passion-fruit flavor. The load-bearing caution is ripeness - the unripe fruit and the foliage contain cyanogenic compounds and are mildly toxic, so only fully ripe fruit (typically gathered after it has dropped, when the rind is wrinkling) should be eaten, and the leaves and green fruit should not.

Apios americana

Groundnut

A herbaceous, tuberous perennial vine of eastern North America that twines 8 to 16 feet up surrounding vegetation through moist thickets, bottomlands, marsh and streambank edges. From mid-summer into fall it carries fragrant, maroon-to-reddish-brown pea-like flowers in compact racemes from the leaf axils, followed by edible seeds; the underground tubers are an edible, protein-rich staple long gathered as Indian potato. A native legume and a documented larval host for the Silver-spotted Skipper, it spreads vigorously by seed and tubers.

Sunchoke

A tall, tuber-forming perennial sunflower native to eastern North America - also called Jerusalem artichoke or sunroot - grown both for its 2-4 inch bright-yellow late-summer sunflowers and its knobby edible underground tubers. Rough-hairy stems rise 6 to 10 feet bearing ovate, serrate leaves on winged petioles. It spreads aggressively by rhizome and self-seeding to form colonies; Missouri Botanical Garden flatly calls it "weedy and invasive" and difficult to remove once planted.

Passiflora incarnata

Maypop (purple passionflower)

A fast-growing, tendril-climbing native vine of the eastern United States, named "maypop" for the fleshy egg-shaped fruits that pop underfoot. Its intricate 2.5-inch fringed flowers - white-to-lavender petals beneath a pinkish-purple filament crown and a raised central androgynophore - are precisely engineered for large carpenter bees. Woody in warm-winter climates and herbaceous (dying to the ground) where winters are cold, it climbs to 6 to 8 feet on a trellis and produces edible yellowish maypops in fall.

Vitis vinifera

Wine grape

The European wine grape - the woody deciduous vine behind nearly all of the world's wine, table grapes, and raisins. It climbs by branched tendrils and, left unpruned, can reach 40 to 60 feet, but vines grown for fruit are pruned hard to a 3-9 foot framework. Ovate, lobed leaves give way to dense clusters of soft pulpy berries that ripen in summer; the plant is high-maintenance, demanding annual pruning, support, and disease management in humid climates.

Musa acuminata

Banana

A giant herbaceous perennial from Southeast Asia and the principal wild ancestor of most cultivated dessert bananas. What looks like a trunk is a 'pseudostem' - tightly rolled leaf sheaths - topped by a fountain of huge, paddle-shaped leaves that can run 6 to 10 feet long, giving an instant tropical effect. In frost-free climates (USDA zones 10a-11b) an established clump produces a drooping flower spike and a hanging bunch of edible fruit, then that pseudostem dies and is replaced by a sucker from the base. It is frost-tender: everywhere colder it is grown as a bold container or greenhouse foliage plant that is overwintered indoors and rarely, if ever, fruits.

It climbs 15 to 30 feet and can fill a 200 sq. ft. trellis in time, carrying large rounded leaves and slightly fragrant cream flowers that open on year-old wood in late spring. It is dioecious: a male pollinizer must be grown alongside female plants for fruit to set.
