Basin Big Sagebrush: The Ultimate Low-Maintenance Native Shrub for Western Gardens
If you’ve ever driven through the American West and marveled at those silvery, aromatic shrubs dotting the landscape, you’ve likely encountered basin big sagebrush (Artemisia tridentata tridentata). This hardy native perennial shrub is making waves in the gardening world, and for good reason – it’s practically bulletproof once established and brings authentic Western charm to any landscape.
What is Basin Big Sagebrush?
Basin big sagebrush is a native North American shrub that’s been thriving in harsh conditions for thousands of years. This tough customer is a true perennial, meaning it comes back year after year, growing as a multi-stemmed woody plant that typically reaches about 9 feet tall and wide at maturity. Don’t expect instant gratification though – this is a slow-growing plant that takes its sweet time, but the wait is worth it.
The plant goes by several scientific names historically, including Artemisia angusta and Seriphidium tridentatum, but Artemisia tridentata tridentata is the accepted name today.
Where Does It Naturally Grow?
This shrub is a true child of the American West, native to both Canada and the lower 48 states. You’ll find it naturally growing across an impressive range including Alberta, British Columbia, Arizona, California, Colorado, Idaho, Massachusetts, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming. That’s quite the geographical footprint!
