Verbena in Zone 8a & 8b
Glandularia spp.
When to plant verbena in zone 8b
Zones 8a and 8b 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 | Jan 14–Jan 21 |
|---|---|
| Direct sow / transplant outside | Apr 1–Apr 8 |
| Estimated bloom | Jun 20–Jun 27 (~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 8's season
Zone 8b's frost-free window runs about 230 days, from March 25 to November 10. Verbena needs about 80 days from sowing to first harvest.
