Passiflora caerulea Constance Elliot- Passion Flower

Passifloras are quite delicate to grow as they are susceptible to frost. The caerulea 'Constance Elliot', undoubtedly the most resistant variety, can withstand frost up to around -5 °C (23°F). It can therefore remain in the ground, in a sheltered position, along a south-facing wall. Take care to mulch it well before the first frosts. Cut it back to the ground in severe frost at the beginning of spring. Otherwise, prune it severely as the flowers appear on the new shoots. It won't hold it against you: it grows quickly and can grow up to 4m (13ft) per year. Apart from its fear of extreme cold, it is hardy and easily adapts to sunny positions. It prefers a relatively poor, well-drained soil.
