Idaho Gumweed: A Hardy Native Wildflower for Western Gardens
If you’re looking for a tough, low-maintenance native plant that can handle whatever Mother Nature throws at it, let me introduce you to Idaho gumweed (Grindelia nana var. integerrima). This plucky little perennial might not be the flashiest flower in your garden, but what it lacks in drama, it more than makes up for in resilience and charm.
What is Idaho Gumweed?
Idaho gumweed is a native perennial forb – that’s gardening speak for a non-woody flowering plant that comes back year after year. Unlike shrubs or trees, this plant stays relatively low to the ground and doesn’t develop thick, woody stems. Instead, it forms a compact mound of foliage topped with cheerful yellow flowers that look like tiny sunflowers.
The gumweed part of its name comes from the sticky, resinous buds that feel tacky to the touch. Don’t worry – this isn’t a sign of an unhealthy plant! That gummy coating is actually the plant’s clever way of protecting its developing flowers from harsh weather and hungry insects.
Where Does Idaho Gumweed Come From?
This hardy wildflower is a true westerner, native to six states across the northwestern United States. You’ll find wild populations growing naturally in Idaho, Montana, Nevada, Oregon, Utah, and Washington. As a native species to the lower 48 states, Idaho gumweed has spent thousands of years adapting to the challenging conditions of the American West.

The flowers provide nectar for native bees and butterflies, while the seeds may attract small birds.
