Here is a link that might be useful: Grassy Knoll

Thanks....I broke down and ordered another actinia from grassy knoll....the first one I ordered years ago,grew like a weed, but never flowered....I'll try again. I've given up on coccinea in favor of a vitifolia...but the two hybrids are still eluding me! I'd pay good money for a confirmed clone of either one. Now, only P. membranacea to add...and I have just the shady spot for it. Thanks again.....any and all passiflora nurseries any one knows of, please post!

Grassy knoll is the best nursery I've found. Ebay can be good, with the standard 'watch who you buy from' warning. 'Strange wonderful things' & "Zostropz" occasionally have membraceana for sale, in a decent size. Both of them pack well & ship quickly.
Looking for seeds? I searched a while back & built a list of worldwide sources here.

Thank you. I may very well end up ordering some seeds from soe apparently hard to obtain species, like cumbalensis,umbilicata and pinnapistula. Aloha Tropicals has membranacea and I just ordered it.....I have an almost complete list now of passiflora nurseries that sell online..let me know if you'd like them.
