Expert tips
The key tip
Passiflora subpeltata climbs quickly and needs light support: guide it onto a trellis from planting onwards. Water regularly during growth, reduce watering and keep it dry in winter.
The common mistake
The trap is letting it stretch out of control: it becomes a messy tangle with few flowers at the top and bare stems at the bottom.
The pro's trick
Pinch the stems regularly in May/June to force lateral branching: more stems means more flowers.
Care
Light exposure
Install your passion flower in full sun for optimal flowering: at least 6 hours of direct daily light. It tolerates partial shade, but will flower less generously. Protect it from strong winds that can damage its flexible stems.
Watering
Water regularly during the growing season (spring-summer) while keeping the soil moist but not waterlogged. Reduce watering in autumn-winter. Ensure good drainage to prevent root suffocation. In hot weather, watering every 2 to 3 days may be necessary.
Pruning and training
Prune lightly after flowering to control shape and encourage branching. Pinch young stems to promote denser growth. Train stems onto a support (trellis, pergola) as they grow. Remove dead or damaged branches.
Fertilizing
Apply balanced fertilizer every 2 to 3 weeks during the growing season (April to September). Use potassium-rich fertilizer when flowering to stimulate flower production. Reduce feeding in winter.
Soil and repotting
Use light, well-draining potting mix enriched with compost. In containers, choose medium-sized pots with drainage holes. Repot every 2 to 3 years in spring. In garden soil, loosen the earth well and add compost at planting time.
Pests and diseases
Watch for spider mites and mealybugs, especially in dry air. Ensure good air circulation around your plant to reduce the risk of powdery mildew or rot. If infestation occurs, isolate the plant and treat with appropriate gentle methods.
Did you know?
The passion flower is called the 'Flower of the Passion' because its floral structures were associated with the Christian symbol of the Passion of Christ: the radiating filaments represented the crown of thorns, the stamens the nails of the crucifixion. This symbolism shaped its name in many European cultures in the 16th century. Some species also produce delicious edible fruits, attracting butterflies whose caterpillars feed on them, making it a valuable host plant for ecosystems.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
