Answer: In my experience the annual vines all need full sun to grow and bloom their best. If you can plant the vine in the ground, or have a very large tub such as a half barrel, you might want to try one of the perennial flowering vines. Sweet autumn clematis, trumpet creeper, and the red-flowered honeysuckles (available from Burpee, http://www.Burepp.com or 800-888-1447) would all bloom well in partial shade. The honeysuckle in particular blooms over a very long season.
