I need to know a good dwarf shrub (approx. 3' tall) to plant in a shady area and an area that stays damp most of the time.
Cephalanthus, aka buttonbush; Clethra "Hummingbird" and other compact varieties; rhododendron and azalea compact/dwarf varieties and Daphne. Do an internet search for compact shrubs for shade in zone ??? You don't give where you live, something vital for choosing a plant.
