I have had this for years. It was supposed to be Vitifolia But it doesn't have grape like leaves and they are not shinny. The leaves are oval and fuzzy. I think the bloom is prettier than other Red's I've seen though.
I was going to say p. vitifolia also. Passifloras can have different leaf shapes on the same vine, and they can change as the vine gets larger and more mature. This leaf shape looks like yours: http://davesgarden.com/pf/showimage/74426/ It could be a hybrid of P. vitifolia and something else.
You should have SOME of the lobed leaves by now if it were P.viti... they are not *real* glossy, but not fuzzy either, in my memory. The flowers REALLY want to 'reflex' (like in this pic) unless something is behind/under the flower stopping the petals from going back.
Actually, I found the one I was thinking of, and the leaves of THAT unknown (which turned out to be P.jamesonii) were even MORE glossy and perfect than P.viti...
But how about Passiflora coccinea? http://toptropicals.com/pics/garden/vines/0028.jpg
The angle of your photo doesn't show the 'height' of the pistil/stamen apparatus, but the leaves in the linked pic (from Top Tropicals, a site/catalog that has solved many i.d. unknowns for me!) sure look similar... I see the petals do want to 'reflex' somewhat, but still not to the degree of P.viti.
What do you think?
Remember, if you want to raise [caterpillars] as well as attract USA butterflies, plant a NON-red passi along with this one!
Yes, those leaves threw me off, too, but NOW I think the smooth-edged pointy leaves all around the flower belong to something else! Look at the one leaf peeking out at the bottom of the pic: http://davesgarden.com/pf/showimage/21485/
Clare and Spin,
Wow thanks for the input. I think I'll try to get another photo in the morning. Looks like it might be coccinea. I'll try to get a better pictur of the leaves as well. I don't think any of these have grape shape leaves and this vine is large on our fence. It is about four years old and the first time it has bloomed. I'm sure I have neglected it some how. Maybe too much shade. I have seen one recently under a porch that blooms like crazy though. I had told Allen this Spring that if it didn't bloom this year it was out a here. LOL We both think thats real funny.
Yes, I agree. Spin, you are right that those leaves belong to something else and just threw me off too. The one at the very bottom is the true leaf of the vine. I don't remember all those other pics either and thought just Thaumaturgist's pics were there! LOL!
Tami, it is well-known that a tree will sometimes flower profusely right before it dies as an attempt to propagate and continue the survival of the species; however, I do not recommend stressing a tree to that degree! I've heard people say that plunging a spade into the roots of wisteria will make it flower, but in actuality, this is just stress which will postpone flowering in the longrun. Lack of full sun is the number one reason why wisterias will refuse to flower.
