Verbena is a low, spreading groundcover flower, 6 to 12 inches at most, that does most of its work at ground level, filling gaps between taller plants and covering bare soil with tight, flat-topped clusters of small purple, pink, red, or white flowers through the hot months.
How verbena fits zone 10's season
Zone 10b's frost-free window runs about 324 days, from January 30 to December 20. Verbena needs about 80 days from sowing to first harvest.
