Idaho Gumweed: A Tough Little Native Wildflower for Water-Wise Gardens
If you’re looking for a low-maintenance native wildflower that can handle tough conditions while still putting on a cheerful show, meet Idaho gumweed (Grindelia nana var. nana). This hardy little perennial might not have the flashiest name, but don’t let that fool you – it’s a garden gem that deserves a spot in water-wise landscapes across the western United States.
What is Idaho Gumweed?
Idaho gumweed is a native perennial forb, which is just a fancy way of saying it’s a non-woody flowering plant that comes back year after year. As a member of the sunflower family, it produces bright yellow, daisy-like blooms that add cheerful color to the garden from summer into fall. The plant forms compact clumps of silvery-green foliage that stays attractive even when not in bloom.
You might also see this plant listed under its botanical synonyms Grindelia nana var. integrifolia or Grindelia squarrosa var. integrifolia in older references, but they’re all the same tough little wildflower.
