13 Stunning Passionflower Varieties

Who could resist a passionflower with a name like 'Silly Cow' This RIVERSIDE hybrid® has an eye-catching "skirt" of dark purple filaments over light petals. The vines are evergreen in zones 8 to 11 and reach 10 to 20 feet.

Vigorous 'Sunburst' vines have blooms with unusual, orange corona filaments and green sepals. The leaves are sprinkled with yellow spots, sometimes called "nectar dots," and stripes, and they're purple underneath. Give your passionflowers well-drained soil; most benefit from feeding with a balanced fertilizer in early spring and again in midsummer.

Passionflowers (Passiflora spp.) are exotic, fast-growing vines. These tropicals grow wild from South America to Mexico and come back as perennials in frost-free regions. In the North, they'll succumb to frost unless you overwinter them indoors. Try them in hanging baskets, containers or garden beds. If they're in the ground, support them with a trellis or fence, or let the vines weave through other plants. Most need full sun, but some can take afternoon shade in hot climates.

Hardy in zones 7 to 11, passionflower 'Inspiration' is a hybrid loaded with light to deep purple blooms. The vines grow 10 to 15 feet and are a good choice for containers. If you grow your passionflowers in the ground, mulch them deeply to help them survive the winter cold.
