Tropical vine for part shade?
I am looking for suggestions for a tropical flowering vine that I could train on an obelisk in the middle of an existing bed that gets dappled morning sun, stronger late morning sun, then shade from a Japanese maple in the afternoon. I like mandevillas but I thought they neded full sun. I also like bougainvillas, but again, full sun for best flowering and growth. Any ideas ?? The other plants in this bed are pastels, not bright reds/oranges, so I would prefer anything in the pink/purple range that flowers all summer. Not a tall order or anything, right?!
Thanks in advance for any suggestions you may have!
