How large of a container are you planning to use? Most vines get quite large and would require a very large container to grow in. The vine would also need some type of support on which to grow. Also, how dense is the shade the rest of the day? Few perennial plants or vines flower well in dense shade. You may be better off planting something will colorful foliage that would be attractive all the time. Heucheras and heucherellas would be good choices. You could combine them with a groundcover that would drape down over the edges of the container. Vinca major, lamium, and lamiastrum are possibilities.
