How to tell between P.incense and incarnata?

mrao77(TX US zone 7)April 13, 2006


How do you differentialte between all of the purple flowering passifloras, since there are so many out there? Obviously, I am a novice to these beauties and have difficulty identifying them correctly.

The one I have is hardy in zone 7, suckers profusely, does not produce fruit (not self fertile, have never pollinated it by hand, should I try? )and the flower is very fragnant. The leaves have 5 lobes, three when the plant is small. ID please?

Flowers from Incese are bigger and deeper purple than incarnata. Here's a link that shows the two flowers side-by-side.

The key is to look at the nectar glands on the petioles. On Incanata they are touching the base of the leaf, on Incense, they are in the middle.

You've got an incense. Incarnata generally have (but not always) three-lobed leaves, while incense generally have (but not always) five lobed leaves. And if the flowers are very strongly scented, that's an incense trait as well.

Incense are pollen-sterile, as I understand it. They will sometimes set fruit if pollinated by caerulea or incarnata, and can produce F2 hybrids, but this is difficult and not too common. Any fruit produced generally has only a few seeds in it.
