Tonight there is a bud on it, and it doesn't look similar to those of any of the plants mentioned so far. Yes, the leaves are rough and papery. Sorry to have confused people with two posts. I'll be sure not to do that again. Thanks again for all the help. Can't think where I got the seed that produced this plant.

I'm totally with Fatamorgana on this one re kids. It's one of the first plants my mother taught me and it was made very clear it was not to be touched. We also had a large Laburnum in the garden and the same rules applied. By the time children are old enough to play out unsupervised they are well past the nibbling stage. It's kids who don't get this kind of understanding who are more likely to do and eat stupid things I believe.

saltcedar, I have one of these right outside my front door...but I don't it is that either, as the leaves seem too large! But it's been 'the best guess so far', thanks! And I will look again to make sure, once the very heavy rain stops. The leaves on J intererrima change shape, as it grows, which I'm sure you're aware of. It would be nice if it was some more of these as I am always taking cuttings to start for friends. Below is a photo of a Ruby Throated hummer resting on the Tree.

It's in a fairly shady spot on the west side of a fence - so no chance of any direct light in the morning and little in the afternoon due to neighboring trees. Thought this was why the original vine was so lethargic, but the children don't seem too hampered by the lack of light and are pretty well covered with buds even in the shadiest areas. The new vines have just topped the fence where they can catch significantly more light, so waiting to see if that changes things. The flowers are very pretty, though small and inconspicuous. I like the large-leaf foliage in contrast to our coral honeysuckle, cross vine, clematis, and VA creeper and hoping it will eventually fill out enough to support some cats.
