Here's an idea - get an itea for your medium to wet soil area, be it in full sun or partial shade. It can adapt to mostly shade if it must but keep it in a moist area. It's extremely compact and round with fragrant, tiny white flowers on cylindrical shaped stems. They cover the shrub when they bloom in the late spring and early summer! Keep an eye on the leaves for they turn radiant shades of red, purple and orange for fall delights, often lasting well into winter.
