It is a robust evergreen climber growing to at least 6 m (20 ft) with three-lobed leaves and pendent deep pink tubular flowers followed by egg-shaped yellow fruits. It is hardy down to about −1 °C (30 °F) so may be grown outdoors with shelter in mild temperate areas; alternatively under glass, for instance in an unheated greenhouse.

Passiflora × exoniensis has won the Royal Horticultural Society's Award of Garden Merit.^[3][4]
