Which passion vine species are safe for caterpillars?
First, it depends on the species of butterfly caterpillar. Some butterfly species can eat and grow on some passion vine species that will kill others.
These are species we have personally raised and did our own experiments with them. If you have raised butterflies on other species, please write to us and we’ll add your information to this page.
The following information was supplied by Donald Burtschi. “I’ve had Varigateds and Gulfs on Incarnata, incense, Caerulea, Foetida, Lutea and several forms of Pallida. I’ve also had Gulfs on Morifolia, Bryonioides, Arida and Ciliata. I’ve only had the opportunity to raise Zebras and Julia’s once a long time ago as they are very rarely in my area. And they were both raised on Lutea which is what they had laid their eggs on. “
The following have not supported native US butterflies in our trials:
Passiflora alatocaerulea – NONE
GF = Gulf Fritillary
ZLW = Zebra Longwing
VF = Variegated Fritillary
J = Julia
? = Although some have ate well, some did not eat and died
NONE: We have not been able to feed any butterfly species on this plant. They all died. It is toxic to them.
Unsafe or unknown
