Habit: Even with its striking silver leaves and ubiquitous nature, Artemisia ludoviciana ssp. ludoviciana is often an overlooked native plant. This perennial shrub grows between 1-3 ft. tall, the lower leaves are tri-lobed at the tips. The non-showy flowers are yellow and arranged in a nodding inflorescense. Blooms from late summer to early fall.
Ecology: Artemisia ludovicana is a widespread native perennial of North America. The broad range of A. ludoviciana over many different ecosystems has produced much variety and in turn has broken the species into several subspecies.
Growing Conditions: The species can be found growing in a variety of environments from rocky dry soil to wet areas near water, depending on the subspecies.
The common names, white sagebrush and silver wormwood refer to the range of colors the leaves appear from pale green to whitish gray, caused by a soft layer of trichomes (minute hair).
