Geyer's onion is a compact native wildflower that produces small purple-pink flower clusters atop slender stems in late spring and early summer. This drought-tolerant perennial forms neat clumps with narrow, grass-like foliage that dies back naturally in summer after blooming.

In an HOA neighborhood

Geyer'S Onion takes more care to keep looking intentional in a front yard. Maintenance level: low. Consider it for backyard or mid-zone beds rather than the street edge.

Works well in: backyard only.

  • Foliage dies back completely in summer

  • Wildflower appearance conflicts with traditional landscaping

Wildlife value
