Big Root Perennial Geranium
Big Root Perennial Geranium (Geranium macrorrhizum). A fine taller groundcover for sun or shade. Pink flowers in early summer over tidy mounded foliage. Aromatic foliage is avoided by deer and rabbits. Increases rapidly but not aggressively. Orange/red/burgundy fall color. One of the few plants that will thrive in dry shade. As its name suggests, it spreads via thick surface roots and can be very easily removed if it spreads into areas where it is not desired.
