Bolander's yampah is a compact native wildflower with delicate white umbrella-shaped flower clusters that bloom through summer. This drought-tolerant perennial grows in neat clumps with fine foliage and requires minimal water once established. It naturally goes dormant in fall, returning each spring from its taproot.
