Growth Habit: Bushy perennial, 4 to 18 inches tall, with extensive creeping rootstocks.

Leaves: Deeply lobed and toothed, alternate, 2 to 5 inches long; upper surface smooth and dark green, lower surface silvery-green covered with minute white hairs.

Flowers: Male and female flowers are found in separate locations on the plant. Male inflorescence is stalked and elongated or spike-like. Female flowers are found in clusters or singular in the axils of the upper leaves.

Roots: Taproot and aggressive creeping rootstocks that sprout new plants.
