Spotted geranium is the wild cranesbill of eastern woodlands, carrying loose clusters of lavender-pink flowers over deeply cut leaves in late spring. Geranium maculatum is a native perennial growing 18 to 24 inches tall and wide in full sun to part sun, hardy from Zone 3 through Zone 8.
Bloom lasts several weeks in May and June, at a point when the spring ephemerals are finishing and the summer perennials have not started. Bees come to the flowers, including specialist bees that use this plant and few others.
The leaves are palm-shaped and deeply cut, often blotched with chocolate-brown, and they turn red in fall.
This grows wild at woodland edges and in open woods, so it handles part shade and root competition, and it also takes more sun than most woodland plants if the soil stays moist. It self-sows modestly into a colony, which suits a naturalized planting. Deer leave it alone.
