Seaside sandmat is a low-growing annual succulent that forms spreading mats of small, fleshy leaves. This coastal native thrives in sandy, well-drained soils and produces tiny flowers from summer through fall. It naturally dies back each winter and may reseed itself in favorable conditions.
In an HOA neighborhood
Seaside Sandmat 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.
- Very informal groundcover appearance
- Annual that dies completely each winter
- May look sparse or patchy in less ideal conditions
Wildlife value
The small flowers attract beetles and flies during the long blooming period from July through October.
