Pursh's rattlebox is a native annual wildflower that grows 1-2 feet tall with bright yellow pea-like flowers from May through August. This drought-tolerant plant thrives in full sun and requires minimal water once established. The name comes from the seed pods that rattle when mature.
In an HOA neighborhood
Pursh's Rattlebox 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.
- Name includes 'rattlebox' which sounds concerning
