Botanical Name

PASSIFLORA quadrangularis

Plant Common Name

Giant Granadilla

General Description

This spectacular, large-fruited woody vine is native to both South America and the West Indies, although its origin is debated because it was cultivated so early and may have traveled somewhat as cultures discovered its crop. In any case, this is a tropical climber that may survive colder conditions where it will die back to the ground and recover from the roots. The plants are evergreen, sprouting into long stems that root as they touch ground, with the potential to be somewhat invasive. The leaves are lobed, dark-green and leathery, but born somewhat sparsely. The vines can become very large and climb by tendrils produced in the leaf axils (joint between the leaves and stems).

The gorgeous flowers are produced singly or in pairs. They have prominent, pronged reproductive structures surrounded by an exceptionally large cup-shaped fringe of dense showy filaments striped in purple and yellow green. They are absolutely exquisite close up. This is a long bloomer, showing color nearly all year around in frost-free climates where it thrives. The large greenish yellow to orange fruit are the size of a hefty garden cucumber and are sweet and delicious when ripe. While plants can be grown in a sunny room or greenhouse they are really too large to perform there. Generally, they prefer full sun and well-drained soil. Grow passion vines on trellises or other supports for the lovely flowers and abundance of butterflies and hummingbirds they attract. Passionflowers are nectar sources and the leaves are larval food for several butterfly species, but the caterpillars can cause the leaves to look tattered and chewed.
