I'm in Zone 7B (Atlanta, GA area) and want to plant some shrubs that will tolerate complete shade under my deck. The red Georgia clay soil will be amended with compost and I can add an irrigation zone. I plan to use Cast Iron Plant underplanted with creeping dead nettle, hostas and ferns but would like some suggestions on other shrubs that might survive complete shade. Thanks!

Japanese Kerria or oakleaf hydrangea might work.

Hostas are not happy in deep shade.........

Slow leggy growth is the long term effect here at my home. Drainage is possibley the most important issue. Besides Iron Leaf in our extreme shade we have Gold Dust Acuba and Fatsia Japonica. We live under a heavy deciduous canopy, so our sunlight comes in the winter months.
