Passiflora seeds

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.
