Roundleaf phacelia is a low-growing annual wildflower that produces clusters of small blue to purple flowers from late spring through summer. This compact native plant forms neat mounds and naturally reseeds itself each year. It is drought-tolerant and requires minimal water once established.
In an HOA neighborhood
Roundleaf Phacelia 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.
