From the article: Dry Shade Plants
Dry shade is one of the toughest conditions to garden in, probably because it's usually under a tree. Still, there are some hearty plants that will compete with the tree roots and laugh off the lack of sun and water - at least for awhile.

Hosta
- Hosta plants are great for dry shade. Though the flowers are not showy, the variety of leaf color available is endless. By planting in 3 different color varieties, you have a colorful show spring, fall and winter. They are very drought tolerent and spread their thick fleshy root so you can divide for free plants under other trees!

Begonias, columbines, and oxalis.
- Some of the plants I've had success with in shady, very dry places are are begonias, columbines, and oxalis. I resisted the old-fashioned begonias until I noticed how well they did in places that were untended most of the summer. Columbines aren’t annuals, but can do surprisingly well almost anywhere with a little shade (if your summers are very hot). They bloom off and on all summer and reseed freely. Native oxalis will bloom all summer and come back for years. All do well with little to no attention. Hope this helps.
