Purple Passion Flower

The roots of the passion flower are prone to rot in cold and wet conditions, they need special care in winter. Ideal compost is a free-draining, soil-based mixture of equal parts sharp sand or gravel, medium or coarse peat, and loam. If grown outside, the passion flower needs a well-drained, dry, and slightly acidic soil. Full sun is essential.

Frost, in long spells, can damage the passion flower’s roots. In such conditions, it may be advisable to place some heat around the roots.

The passion flower can be propagated by seed, or by cuttings. Seeds from the passion fruit can be grown either under glass or in a tub placed outside from May to September. After removing the arils (outer covering) from the seed, they should be sown onto a standard potting compost. Germination occurs within two to three weeks. Plenty of water and monthly feeding is required till the plant starts flowering.

The beauty of its flowers, and the unique flavors of its fruit, have made the passion flower a popular choice for cultivation over the centuries. Hybridization has been extensive. The passion fruit or maracujŠ vine of commerce, Passiflora edulis, is cultivated extensively in the Caribbean, south Florida, and South Africa for its fruit. The maypop, Passiflora incarnata, is grown in gardens in southern United States.

The Chilean passiflora, Passiflora pinnatistipula, grows in the Andes, from Venezuela to Chile, in high altitudes (2,500 to 3,800 meters), and in coastal central Chile. This species is grown in the similar climatic conditions of Monterey Bay, San Francisco, and the western coast of the U.S.


Passion Flower – Cultivation and Propogation

The passion flower (Passiflora) is a perennial vine that grows in the wild, in well-drained areas. It is found abundantly on the slopes of the Andes, the floor of the rainforest, and in roadside rubble in arid conditions.

Because it enjoys an arid environment, the passion flower is relatively easy to grow - more so in conservatories and greenhouses than as indoor plants. The root system is small and when grown in fair-sized pots (about 10 inches), the passion flower can grow to a decent height. As the passion flower is a climbing vine, a trellis is required for support.

For germination, fresh seed works best. The seeds need to be sandpapered and soaked in tepid water for a day. They then need to be sowed 2-5 mm deep in a peat or soil-based seed compost. Temperature is critical and should be maintained at 20 degrees C (68 degrees F) for 16 hours and 30 degrees c (86 degrees F) for 8 hours a day. Fresh seeds germinate in two to four weeks. Older seed takes almost double the time.

For cultivation, cuttings of the passion flower can also be used. They are easily rooted from the plant, and best taken in early spring. A cutting of the tip or end shoot of the passion flower is ideal. It is important to cut close below the node of the first or second mature leaf from the end shoot. After removing the bottom leaf and all tendrils and flower stalks, the cut end must be dipped in rooting powder and then inserted a half-inch deep into the compost.

Nodal cuttings are also useful. They should be two or three leaves long with the bottom leaf and tendril removed. Numerous cuttings are possible from one shoot.
