This perennial vine, also known as the maypop, begins popping out of the ground in May and lasts until the first frost, at which time it is killed back, only to return in full force the following spring. The passion flower showcases three-inch-wide flowers in vibrant colors such as hot pink, coral, yellow and purple, and this fast grower can get up to 15 feet high, making a trellis or fence a must when planting it. Butterflies and hummingbirds are attracted to this very attractive flower often used dried in herbal teas.
Grow your passion flower in full sun, with some partial shade in mid-summer when the weather is the hottest. Plant it near a trellis or fence for it to climb up as it quickly grows in the spring.
Keep your passion flower watered continuously, so the soil stays moist. Use a drip irrigation system to water deeply, letting the water run for about one hour each week. Be sure the soil has excellent drainage so it does not become soggy. Passion flowers will grow in almost kind of soil as long as the roots do not become waterlogged.
Apply a layer of mulch around your passion flower, not only for aesthetic reasons but to help the soil retain moisture and maintain an even temperature. Mulch can include shredded bark, pine needles or straw.
Feed this vigorous grower with a balanced liquid fertilizer (20-20-20). Apply fertilizer in the early spring after the last frost and again in early summer, and water it in well.
Prune your passion flower in early spring to encourage lots of new growth. After the last frost, prune the vine to about six inches above the ground, or leaving six to eight buds on the plant.
