What Makes Parsnipflower Buckwheat Special?

This native beauty belongs to the buckwheat family and has earned its keep as a true survivor in the challenging landscapes of Idaho and Washington. As a perennial forb, it returns year after year without the woody stems of shrubs, instead forming lovely clumps of silvery-gray foliage topped with clusters of delicate white to cream-colored flowers.

Parsnipflower buckwheat is native to the lower 48 states, specifically thriving in the rugged terrain of Idaho and Washington. This regional specialization makes it particularly valuable for gardeners in these areas who want to create landscapes that truly reflect their local ecosystem.

  • Ground cover applications

Growing Conditions and Care

One of the best things about parsnipflower buckwheat is how little fuss it requires once established. This plant is practically the definition of set it and forget it gardening:

  • Avoid fertilizing, as this plant prefers lean soils
