Passiflora caerulea is a woody capable of growing to 15–20 m (50 to 65 ft) high where supporting trees are available. The leaves are alternate, palmately five-lobed like a spread hand (sometimes three or seven lobes). The base of each leaf has a tendril which twines around supporting vegetation to hold the plant up.
The flower is large, about 10 cm (4 in) in diameter, with the five sepals and petals similar in appearance, whitish in color, surmounted by a corona of blue or violet filaments, then five greenish-yellow stamens and three purple stigmas. In tropical climates, it will flower all year round. The ovoid orange fruit, growing to 6 cm (2 in), is edible but bland.
Passiflora caerulea is widely cultivated as a wall-climber or as groundcover. It has gained the Royal Horticultural Society's Award of Garden Merit!

Note: This plant species is known to have toxicity. ornamental use only.
Seeds per pack: 5
Germination: As with many hardy perennials, these seeds benefit from a period of moist cold to help them grow. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:
First, soak your seeds in orange juice for 12-24 hours before planting. This helps soften the hard outer coating on the seeds. Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds just under the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 5-6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.
Alternatively, these seeds can also be planted outdoors in fall, winter, or early spring, while temperatures are still cold (but ground is workable) to germinate naturally in spring. Be sure to mark the area where you planted them, and that the soil is consistently moist.
