Research says it is evergreen. But I know it to look crappy in winter so it gets cut back hard. I had one at our old rental house in Arcadia in a whiskey barrel and would let it climb up a Eucalyptus tree. But the whole thing was too big to fit in our large(the largest) moving truck. So, I left it with my neighbor. Then I hunted nurseries here in Burbank(only 23 miles away) for 2 years unsuccessfully. I finally mail ordered a tiny 4" pot of it. I wasn't sure where to plant it, just knew that I needed it :-) So I planted it on the birch teepee in the front yard on which I also have a climbing rose called Bouquet Parfait.
You can barely see the teepee. There are 3 legs.
