Arrowhead rattlebox is a low-growing annual wildflower with arrow-shaped leaves and bright yellow pea-like flowers that bloom through summer. This native plant tolerates drought well and produces distinctive seed pods that rattle when mature. It naturally reseeds in sunny, well-drained locations.
In an HOA neighborhood
Arrowhead 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.
