PURPLE PASSION FLOWER Passiflora incarnata
This is the hardiest Passion Flower that we carry, and probably the hardiest available! These exotic-looking flowers are amazingly wavy, and have a stunning blue-purple color. Plants will gently cling to surrounding structures or shrubbery, and climb up to 20'! Flowers appear in summer, and continue throughout the growing season.
Hardiness zones: 5-9
Type: Climbing Vine
Location: Sun or part sun
Seeds per pack: 5
Note: This plant species is known to have toxicity. ornamental use only.
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.
