Ross’ Avens: A Tough-as-Nails Native for Rocky Gardens
If you’re looking for a hardy native plant that laughs in the face of drought and rocky soil, let me introduce you to Ross’ avens (Geum rossii var. turbinatum). This plucky little perennial might not win any height contests at just under half a foot tall, but what it lacks in stature, it makes up for in resilience and charm.
Meet Your New Alpine Friend
Ross’ avens is a true native of the American West, calling home to nine states across the region: Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, and Wyoming. This tough little forb has adapted to some of the harshest growing conditions imaginable, making it a fantastic choice for gardeners who want beauty without the fuss.
As a perennial herb, Ross’ avens grows as a low, spreading ground cover that reaches about 0.4 feet in height. Don’t let its modest size fool you – this plant has a rhizomatous growth form, meaning it spreads underground to create lovely carpets of fine-textured, green foliage topped with cheerful yellow flowers during summer.

A Few Things to Consider
While Ross’ avens is generally wonderful, it’s not right for every situation:

- Has low fire tolerance when actively growing
- May not be readily available commercially
- Short-lived perennial, so expect to replant or allow self-seeding
The Bottom Line
Ross’ avens is a fantastic choice for gardeners who appreciate native plants and want something truly adapted to challenging western growing conditions. Its cheerful yellow flowers, drought tolerance, and ability to thrive where other plants struggle make it a valuable addition to the right garden. If you have a sunny, well-drained spot that needs a tough, low-growing native plant, Ross’ avens might just be your perfect match.
Just remember – this is a plant that’s evolved for mountain conditions, so give it the lean, well-drained soil it craves, and it will reward you with years of reliable beauty and beneficial habitat for native pollinators.
