Come! Ms. Dunlap will give two talks at the CNPS Conservation Conference Feb. 1-3 in LA!

One regarding a database of 3,700 nectar plants (& how to collect images to benefit pollinators), and the other regarding
a prototypical key incorporating a novel plant identification system that produced an order of magnitude improvement.

Passiflora x alato-caerulea, passionflower, is a twining evergreen vine with purple flowers - that emerge in summer and fall. This vine does need support on a trellis or arbor and will grow to 16 feet long. It can be propagated by cutting or seed and thrives in Zone 9, preferring well drained soil and moderate watering. Try it in a large container with a trellis.

Passiflora x alato-caerulea is cross between P. alata and P. caerulea. P. x belotii is a hybrid of P. alata and P. caerulea. Both have purple blossoms and grow to 16 feet long. There are other Passiflora that are a bit shorter (Passiflora sanguinolenta and Passiflora manicata) and some that are longer (Passiflora ‘Coral Seas’ and Passiflora edulis). Passiflora edulis is the fruiting species.

Passiflora will attract adult butterflies to feed. If you have this plant, please let us know what butterflies come to feed. Passiflora are also a host plant to Gulf Fritillary, (Agraulis vanillae), a butterfly dependent upon garden plants to survive.

Container plants that attract adult butterflies - vine

This plant is one of 25 vines suitable to grow in a container that can attract adult butterflies. 3 of these plants attract birds and 9 attract specific butterfly species. They can be found in large, medium-large and tiny heights - from less than a foot long to over 10 feet tall. None of these plants are drought tolerant as most of them prefer moderate or regular watering. 7 are deciduous, while 19 are evergreen. Some can grow in Zones 3 and Zone 4, while the others grow in Zones 5-11. 23 vines that attract butterflies and can be grown in containers in Zone 9. None are known to be used as cut flowers. They are available in seven different flower colors.

We encourage you to use additional filters to refine your plant search for butterfly-friendly plants. Most vines grown in containers will need support that enables the vine to climb or twine around the support. Inserting a trellis in the container can work.

There are 221 vines in this database of which this short list of 25 vines can attract adult butterflies and be grown in a container. Most vines are prostrate, so we set their height to "0" while registering the plant's potential length in the width category. The length of many vines can be controlled by human activity.
