giant granadilla · Passiflora quadrangularis
Also known as: square-stemmed passionflower
Under glass grow in a container in loam-based potting compost in full light with shade from hot sun. Water freely when in growth and keep just moist in winter with a minimum temperature of 13°C. May be grown outdoors in frost-free areas in most fertile, moist but well-drained soils and overwintered indoors, see passion flower cultivation
Routine pruning is unnecessary; shorten overlong shoots to fit the available space. For last-year flowering growth, prune after flowering; for current-year flowering growth, prune in late winter or spring. This guidance is for established plants.
