The Passion Flower vine originates from Brazil and Argentina. This tropical beauty has a light fragrance, and the vine also produces a small fruit that is edible and used in many drinks. The Blue Passion Flower can be grown in gardening zone 7 or warmer and can be grown in the ground or containers. It will need a trellis or fence to climb, but also makes a wonderful plant for a hanging basket.
Dig a hole in a location with full sun, a couple inches larger than the pot you purchased your plant in. Amend the dug-out soil with about three handfuls of compost, to aid in drainage. Passion flower does not do well in heavy wet soils.
Install a trellis, if needed, before planting the Passion vine. This will keep you from any of the roots during the installation. If planting near a fence or arbor that's already in place, you can skip this step.
Fill the hole back in with enough amended soil so the plant will sit at the same level with the surrounding ground as it did in the container you purchased it in.
Place the plant in the hole and fill halfway up the root ball with soil. Water to compact the soil around the roots and add more soil. Continue in this fashion until the hole is completely filled, and hand-tamp down.
Water generously to help establish the roots. Water to keep the soil moist through the growing season, once a week through the fall and once a month while the plant is dormant. Dormancy will be different depending on location and average temperatures.
Mist the plant during dry spells to add humidity to the plant.
Fertilize with a water-soluble fertilizer diluted to half strength, twice a week during the growing season and once a month after.
Mulch around the plant each fall with a bark-chip mulch to retain moisture and keep the ground warmer during the winter. The mulch will also help keep the weeds from growing near the plant.
Pinch off flowers as they die to promote more budding, and prune in the late fall to keep the vine within a manageable size.
