Passiflora subpeltata aka White Passionflower

Passiflora subpeltata is a vine that lives for years. It belongs to the passionflower family, Passifloraceae. Its other names are white passionfruit and granadina. Its home range runs from Mexico through Central America to Venezuela. Useful Tropical Plants lists Colombia as part of that range too. Kew places it in the wet tropics. It grows in thickets and hedges, and at times in forest. Records show it at both damp and dry sites. These lie about 3,940–6,560 feet [1,200–2,000 metres] above sea level.

This large vine climbs on plants that grow near it. Its tendrils grip those plants as its stems grow longer. The stems can grow woody, though how much varies. The sources give no firm size for a full-grown plant. This applies to both its height and its spread. They give no bark or leaf shape details for this species. The RHS lists Passiflora atomaria as another name for it. Its wider notes on passionflower leaves cover more than this species.

Gardeners grow this vine chiefly for its white flowers. The sources give no time of year for the blooms. Its yellow-green fruit can be egg-shaped or almost round. Each fruit is about 0.08–0.13 feet [0.025–0.04 metres] across. People eat the pulp that grows round the seeds. Local people also gather the wild plant for food. Useful Tropical Plants rates its food use two out of five. That use applies to the fruit pulp, not all plant parts.

The guide describes how to grow plants from seed or young-shoot cuttings. It says to sow fresh seed with its pulp. Soak stored seed in warm water for 24 hours before sowing. Even then, stored seed may take twelve months to sprout. The guide puts seed trays in shade at 19–24°C. Move each young plant to its own pot when large enough to handle. Take cuttings from young shoots and keep a node on each.

This vine has spread from gardens beyond its home range. Useful Tropical Plants says it invades native habitats in some areas. Weigh that risk against its worth as a vine grown for flowers. The evidence gives no hardiness rating for this species. Nor does it list pests for this species. It reports no known hazards, but does not prove pet safety. Its notes on use as medicine cover other passionflowers. They do not confirm such uses for this species.
