Toxicity: Some parts of the plant may be toxic if ingested by humans or pets
Potential Issues: Can be invasive in some regions; attracts caterpillars that feed on the foliage; may require regular pruning to manage growth
Notes: Passionvine is a vigorous, fast-growing climber known for its stunningly intricate flowers that bloom from spring to fall. These vines are popular in gardens for their ornamental value and ability to attract pollinators. Some species, like Passiflora edulis, also produce edible fruit. Passionvine is commonly grown on trellises, fences, and arbors, and its foliage serves as a host plant for caterpillars, making it a favorite among butterfly enthusiasts. While it can spread aggressively, regular pruning can help control its growth.

Passion Vines are a host plant for the Gulf Fritillary, Variegated Fritillary, Mexican Fritillary, and the Zebra Longwing Butterflies. Please do not use pesticides on them. If you cannot stand it, consider planting two, one for you and one for the butterflies. You can transfer the caterpillars from one vine to the other.
