Hi all, just wondering if anyone grows trumpet vines on their mature trees? I was thinking of trying this, but wonder if they would get too aggressive. I have mostly mature green ash that I'd like to try this on, but what are your thoughts? I have read that the trumpet vines can get severely invasive, but maybe that's in warmer climates. I tried growing one once on my clothesline pole and the thing has barely survived let alone flower or invade anything. I'm thinking it's too shaded there for it though.
