Passion Flower ( Passiflora ) Seed ( Perennial )

Passion flowers are exotic looking topical plants that can actually be grown in much milder areas. There are many different passion flower plants. Some passion flowers are vines, some produce edible fruits. Here are some tips for growing passion flowers at home.

The genus Passiflora contains over 400 species, so the common name Passion Flower can be a bit confusing. To muddle matters further, most are vines, but some are shrubs, annuls, perennials and even trees. What they all share are exotic flowers that only remain open for about 1 day. They have a wide, flat petal base with several rings of filaments in the center which surround a stalk of sorts, that holds up the ovary and stamens

Passion Flowers are also known as Passion Vine, Maypop, Granadilla and other common names.
USDA Hardiness Zones: 6 - 10, depending on species.
Exposure: Full Sun to Partial Shade. Bloom Period: Mid- to Late Summer.

Passion flowers look extremely exotic, so it's a surprise to find them growing in fields along the sides of the road. There is considerable variety between the species. Flowers: 5 or 10 petals in a flat or reflex circle. The ovary and stamens are held atop a tall, distinctive stalk which is encircled by delicate filaments. The stigmas start out high above the anthers and slowly bend backwards to come closer for pollination. Colors include: blue, purple, pink, white and red.

A lot of gardeners prefer to grow their passion flowers in containers. Passion flower grows quite happily in a pot and you have the convenience of being able to move it to a sunnier site or even bring it indoors for the winter. Plus, it limits the spreading by rhizomes.

Passion flowers should be grown in a container that is overwintered indoors in the cool temperatures of a greenhouse or in the bright light of a home with temperature around 60 F.
For containers, use a well-drained, peat/humusy potting mix. Place containers outdoors in full sun after last spring frost date.
Best flowering in full sun, but tolerates light shade. These flowering vines appreciate high humidity, but needs good air circulation to discourage fungal diseases. Water evenly and consistently during the growing season.
Vines produce flowers on new growth, so they may be pruned as needed early in the growing season. Bring vines indoors before first fall frost date. Reduce watering from fall to late winter. Passion flower may be grown as a houseplant in a sun room or in a sunny south-facing window.

D8564 Passion Fruit ( Passiflora edulis )
Zone 7 and higher. This vine, native to the Amazon, produces beautiful flowers and sweet-tart fruit.

The fruit is produced on a woody vine from bisexual flowers. The fruit is somewhat tart, has a hard purple or yellow rind, and contains many black seeds. Passion fruit is commonly used in beverages.

BM67 Blue Passionflower ( Passiflora caerulea )
Blue passionflower is a twining vine that can grow to 30 ft (9.1 m). The shiny leaves are usually palmately lobed with five parts, but they can have as few as three lobes or as many as nine. They are evergreen in tropical climates, but deciduous where winters are cool. The white and purple-blue flowers which appear in summer may be as large as 4 in (10.2 cm) across. They are followed by egg-size deep orange fruits from late summer through fall.
Blue passionflower likes loose sandy or gravelly soils and does best planted in old brick rubble that retains heat during cold winter weather. Too much manure or compost will result in lush vegetative growth and poor flowering. This species will flower in a small pot, but it prefers plenty of root space and will do better in a roomy container. In Zone 8-9, the ideal location is against a warm south-facing old brick wall where an overhang prevents excessive drenching by heavy rains.
Go light on fertilizer and water deeply, but infrequently; passionflowers should be encouraged to reach deep into the earth for water. When motivated to do so, they are capable of developing amazing root systems to sustain them through droughts and freezes. Passionflowers love high humidity, but they are subject to fungal diseases if they don't get good air circulation in the greenhouse. Blue passionflower does better overwintered in a cool greenhouse where it can go semi-dormant as opposed to in a hothouse where it will be tempted to put too much energy into weak off-season growth. In either case, it is important to keep the soil on the dry side in the winter.
Blue passionflower may be wound around a hoop support to keep it within bounds so that it may be grown as a houseplant in a sunny south-facing window. Passifloras flower on new growth, so they may be pruned early in the growing season. It is best to cut some stems back nearly to the base, rather than just trim the tips. The terminal buds may be pinched out to encourage branching. Always keep some green foliage on the plant to keep the sap rising and encourage rapid regrowth. The roots may be weakened and become subject to fungal infection if too much top growth is removed at once. Don't try to train a passionflower to be too neat and compact; branches allowed to hang loose and droop a bit will be the ones most inclined to flower. Passionflowers are subject to a wide array of pests and diseases, but most of them have minimal impact on well grown plants. Butterfly larvae are the exception; caterpillars readily devour the foliage of healthy mature plants.
Passionflowers like full sun and will scramble over trees and shrubs to get it.
Hardiness: USDA Zones 8 - 11. Blue passionflowers will regrow from deep roots after even severe freezes. They have been known to survive temperatures as low as 5°F (-15°C) when the ground was frozen over two feet deep! It is nevertheless important to keep the soil as warm as possible, especially in the winter greenhouse.
