Many species of native bees are particularly attracted to Passionflowers.

Wildlife Value

Passionflower vines serve as larval host plants for several butterfly species, including Gulf Fritillaries in warmer regions.

The flowers and fruit contribute valuable food resources for wildlife.

Historical and Cultural Facts

Spanish missionaries in South America gave Passionflowers their common name because they believed various parts of the flower symbolized elements of the Passion of Christ.

The corona filaments were said to represent the crown of thorns, while other flower structures symbolized nails, wounds, and apostles.

This symbolic interpretation helped spread Passionflowers throughout Europe and beyond.
