Passiflora Cold Hardy Bundle

Incense:

This is one of the most popular and hardiest Passiflora hybrids available. Incense produces whimsical 3-4” purple flowers with long wavy purple filaments all summer long. In addition to the flowers, this vine boasts very attractive leaves that are unbothered by most insects. The leaves make excellent food for fritillary butterfly larvae if you are seeking a highly ornamental vine for your butterfly garden.

As is common with most cold hardy passion flowers, this vine suckers readily. This means that it will re-sprout from the roots if frozen back to the ground.  Due to this suckering habit, it may also pop up in other places in your garden. Because of this suckering characteristic, and due to its large size, this vine is best planted in the ground somewhere that it will have plenty of space to grow. However, this vine also performs well in a container for those who are located in climates too cold for outdoor planting.

You should definitely plant this vine in the sunniest location you have.  If it is shaded it will not bloom at all.

Additionally, in colder areas, it would benefit from a protective winter mulch.  If grown in a container, it will need to have the roots protected from freezing temperatures.

Incarnata:

The hardiest of all passion flowers. It grows and flowers profusely even in colder climates adding a touch of exotic flare to any garden. In fact, it will even produce edible fruit in northern climates.

Small to medium light purple blooms are produced in abundance all summer long. Despite not having flowers as big as some other varieties, incarnata more than makes up for it with volume. In addition, this is one of the easiest vines to grow, as it will reward you for your neglect with flowers, lots of flowers. If pollinated, the flowers are followed with small fruits you can eat. Best of all, it is a native plant that is pollinator and wildlife friendly. You will likely find, that this vine is a magnet for both pollinators and fritillary butterfly larvae.

When it gets frozen in the fall, it dies back to the ground and reappears in May resulting in its common name ‘maypop’.  Also, it will sucker from the roots and spread sending up new stems where the roots have run to. You can control its spread by simply pulling or cutting down the unwanted sprouts.

You should plant it in full sun and provide it with plenty of water during the growing season to get the most flowers. However, to successfully overwinter this vine, it will need to be located in a well drained spot.
