Passionvine, purple passion flower, maypop (Passiflora incarnata) is a beautiful perennial native vine with a wonderfully complex flower with crimped petal-like tepals. It dies back to the ground in the winter, but pops up in more places the next spring–in May usually. It’s widely distributed from Florida to Texas and northward to Pennsylvania. It can be propagated by cuttings, seed, or by digging up its sprouts when they’ve come up in an inconvenient place.
The plants were given the name passionflower or passionvine by early Spanish explorers because the floral parts were once said to represent aspects of the Christian crucifixion story or the Passion. The ten petal-like parts represent the disciples, excluding Peter and Judas; the five stamens the wounds Jesus received; the knob-like stigmas the nails; the fringe the crown of thorns. The more mundane name “maypop” comes from its sprouting from dormancy in May and that the hollow, ripened fruits that pop loudly when crushed.
Like most gardeners, I love beautiful plants that attract many pollinators. And for a vine like this, adorning the trelliswork is the ideal location. It’s beautiful, isn’t it?
This plant is also the larval host plant for gulf fritillary (Agraulis vanillae), variegated fritillary (Euptoieta claudia), Julia (Dryas iulia) and zebra longwing (Heliconius charitonius) butterflies.
It’s said that if the passionvine grows in the shade, it will attract the zebra longwing, our state butterfly. I haven’t seen many of the zebra longwing larvae, so I can’t really verify that, but I have witnessed a lot of the gulf fritillary activity in the sun or the shade.
The scattershot egg laying gives her hungry offspring a fighting chance to survive. First, if a lizard or some other predator finds an egg, the other eggs are at some distance. Second, the hungry larvae have their own leaf area to themselves at first. Actually the first thing the larva does after hatching is to eat its own egg, but then it gets serious about eating leaves.
Did I say hungry??
Now that vine on the trellis may not so beautiful to others, but for me, I love a moth-eaten or butterfly-eaten landscape. My name is Ginny and I am a butterfly gardener! Won’t you join me as a full-fledged member of Butterfly Gardeners Annoymous (BGA) and proudly proclaim your butterfly-eaten landscape to be beautiful?
