Verbena in Zone 9a & 9b
Glandularia spp.
When to plant verbena in zone 9b
Zones 9a and 9b share the same average frost dates in our data, so this page covers both.
Method: Either: Start indoors for an earlier harvest, or direct-sow outside for less fuss. Verbena tolerates either.
| Start indoors | Dec 7–Dec 14 |
|---|---|
| Direct sow / transplant outside | Feb 22–Mar 1 |
| Estimated bloom | May 13–May 20 (~80 days after planting) |
Spacing: about 2 square feet per plant (square-foot-gardening spacing). Mature height: 0.5-1 ft.
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 9's season
Zone 9b's frost-free window runs about 293 days, from February 15 to December 5. Verbena needs about 80 days from sowing to first harvest.
