I have Little Kim lilacs, a miniature variety, in a woodland area that gets little sun. The lilacs are shaded by a huge maple. They bloom every spring.

I have a Silver Moon clematis that gets only a couple of hours of direct sun and yet still bloomed profusely this year (spring). ALso a Prince Charles clematis that is in a great deal of dappled or full shade throughout the day, yet is actually kicking out a small second show of blooms right now. (First was in early June.)

Coneflowers!

Most of my bearded iris (an unnamed, amazingly tough dark purple variety) are in partial to deep shade. Doesn't faze them a bit, they bloom and rebloom without fail.

I have canna lilies, groundcover roses, fairy roses, pelargoniums, citrus (Meyer lemon and Bearss lime), euonymus, penstemon, tanacetum and osteospermums in beds that are only partial sun.
