Dwarf St. Johnswort is a compact annual wildflower that stays under 16 inches tall with small yellow blooms from June through September. This native plant forms neat, low mounds and works well as a natural groundcover or in mixed plantings. Its small stature and tidy growth habit make it easy to incorporate into landscaped areas.
In an HOA neighborhood
Dwarf St. Johnswort takes more care to keep looking intentional in a front yard. Maintenance level: moderate. Consider it for backyard or mid-zone beds rather than the street edge.
Works well in: backyard only.
