How to Grow and Care
Their vibrant colors and heady fragrance make the Passion Flower a welcome addition to any garden. Unfortunately, because of its origins, most species of Passion Flower plant can't overwinter in many gardens in the United States. However, there are a few that will survive up to USDA plant hardiness zone 5. Most varieties will grow in Zones 7-10.
Because they are vines, the best place for growing Passion Flower is along a trellis or fence. The tops will be killed off during winter, but if you mulch deeply, your Passion Flower plant will return with new shoots in the spring. Since growing Passion Flowers can reach 20 feet (6 m) in a single season, this dies back will help keep the vine under control.
Tropical Passion Flowers need full sun and well-drained soil. Two applications of a well-balanced fertilizer per year, once in early spring and one in midsummer, are all the Passion Flower care you'll need. See more at How to Grow and Care for Passion Flowers.
