Rough hedgenettle is a pretty yet unassuming member of the mint (Lamiaceae) family. It is native to California, Oregon, Washington and far western Nevada, where it grows along creeks, rivers and other moist locations, as well as in the understory of seasonally moist woodland. Rough hedgenettle is a perennial wildflower that grows to a maximum height of 2′-3′ and spreads via slender rhizomes and seed. It has attractive white to pink whorled flower clusters that bloom in the spring. Rough hedgenettle prefers dappled shade. It will need moist soil through the spring but can dry out in late summer, making it somewhat drought tolerant. The flowers of rough hedgenettle are attractive to bumble bees and other native bees, butterflies and hummingbirds. Rough hedgenettle is used as a larval host plant by some butterflies, including checkerspots.
