Winter Hardy Passionflower is a North America species which is easily grown in any humus-rich, well drained soil with sufficient moisture in summer. Plants require a climbing aid as these are growing as wines. If planted freely it will develop its' first flowers after some 3 years and may set deliciously sweet fruits. Passiflora incarnata is fully hardy in central Europe with a thick mulch layer as additional frost protection.
Sow in any well drained, humus rich soil in a sunny spot at some 20°. Cultivate frostfree in the first two years, keep plants drier in winter at some 5°C. Transplant to a sunny, protected spot outside in late spring to early summer.
All are USDA Climate Zone 7.
