Passiflora caerulea

This used to be the most favourite and widely grown of the passion flowers (there are some 400 species). Nowadays, however, when houses are warmer in winter, it is grown less of ten because it is impossible to provide the necessary cold and light conditions.

It requires a fairly heavy compost. Position in full sunlight in spring and summer, otherwise it will not flower. The maximum winter temperature is 10°C (50° F). Prune it hard to promote the formation of new, young flower-bearing shoots. Feed weekly from spring to autumn. Propagate either by seed or by cuttings; only ripe stems, with two leaves, should be taken as cuttings. They will readily form roots at a soil temperature of about 20° C (68° F).
