Hi there,
No reply button on your post about the passionflower so I've started a new thread here to answer your query..
I've just nipped out the back and had a look at mine. Sorry but your looks completely different. My passionflower has longer, thinner palmate leaves.
Don't know what your plant is although it does looks kinda like a camelia doesn't it?
There's bound to be someone else with more knowledge than I have who could point you in the right diection. Hope you get an answer to your question soon.
Eileen.
