Chuck, you are a sweetheart, I really wanted to identify this one. Unfortunately it is not a Texas native
but being evergreen is surely a plus.
Thank you so much.
Josephine.
Glad I did not yank out this vine
Does it need full sun ?
The DG link above shows full sun.
I have a Passiflora with small, greenish flowers that grows in abundance in my yard. Always in shade. I am not clear if it is P. lutea or P. affinis. The vines can get at least 20 feet high, although they often just ramble over the ground and lower shrubs. About two years out of three we get the heliconid zebra butterfly in San Antonio. They blow up out of Mexico. This is the only heliconid that I am aware of to reach our area. This green Passiflora is the host plant for their larvae and two or more generations are spawned during a summer. I love the heliconids. Makes me feel like I'm in the tropics. I'll try to get a photo in the next few days and post (of the plant, no heliconids yet this year).
I have seen a Zebra come through my yard and around this area, but they are few and far in between. I haven't had any egg layers that I am aware of. You are very lucky indeed to have them active at your place. They are beautiful. Do you get the Julia heliconid also?
My Constance Elliott passiflora is mostly in shade. Like most plants, they do better and flower more in full sun though. This is all new growth from the stalks I left on the trellis last fall, and is still in full growth mode. Recently cut off a large pile of 8-10 foot growth climbing the plum and oak tree.
Very lovely Chuck.
Sheila,
Don't know. Just looked the Julia up and I may have seen them. Maybe not. Do they have that same sort of floating/flit flight pattern as the zebra? I'll be looking more closely now. Here's a photo of the Passiflora. I do think it's P. lutea.

Yes I seem to remember they do. I loved all of them in the longwing group. I worked the FW Botanic Garden's tropical butterfly exhibit about three years ago. They are going to have it again this next March 2010, if anyone is interested in attending.
I will take a shot of my lutea tomorrow. see this site: http://www.passionflow.co.uk/passiflora-lutea.htm
My lutea does have this shape leaf. My vines were wild collected. I have never seen a lobed lutea leaf in the wild around here. I wonder if they vary in different regions.
The one shown at the Wildflower center is lobed;

Ladies, I think we have a puzzle. My primary reference is 'Manual of the Vascular Plants of Texas", Correll and Johnston. I admit this is becoming more and more outdated in its taxonomy, but it lists five species of Passiflora in Texas that have small, green flowers: P. tenuiloba, P. suberosa, P. lutea, P. filipes, and P. affinis. I have seen P. tenuiloba in Bexar County and it is not the plant in my photo. P. suberosa is supposedly found only in "extreme s. Tex." in palm groves and thickets; so I don't think it's that one. P. filipes is stated to occur in "palm groves and thickets in extreme s. Tex." Again, by range, I rule out P. filipes. This leaves us with P. affinis and P. lutea. The separation in the key is P. affinis as "Peducles rather stout, provided with bracts that are often early-deciduous..." and P. lutea as "Peduncles very slender, bractless..."

I believe the plant in my photo is Passiflora affinis. What do you think?
Well here is a picture of P. affinis and it had no bracts on the buds and very deep lobes on the leaves,

while this picture of P. lutea shows more rounded lobes on the leaves and no bracts
