We have both the Blue and White. We generally get a frost/freeze that knocks them to the ground. Every year they come back and get to the tops of the trees. I'm sure that if we went thru a winter without a frost or freeze, I'd be wacking them back too. It can kill your tree's if let go too long.
I decided to cut back my sky vine today and it had intertwined with creeping fig that was on house. When I pulled it down off came the paint with it. Now I have speckeled house on one end. Oh well I'm sure creeping fig will grow over it again and then next time when its time to paint I'll cut it all off and then pressure wash.
Happy gardening all.
I wonder if it would overtake my woodland area, here in the desert mountains, it is still hot and dry, so it may not go crazy here. Sure is pretty. We get 4 months of snow off and on, but mostly it is just cold, so maybe it would not be so bad if it dies back in the cold.
I would be really concerned about it messing up the eco-system up there in protected Oak forest, if the experiment went a rye. Gosh, rattlers could live in there and it would be scary to go up the hill to our garage. I am rethinking this plant. Is it like Kudzu?
