Oregano in Zone 7a & 7b
Origanum vulgare
Yes, oregano grows in zones 7a and 7b. Start seeds indoors Feb 13–Feb 20 and plant out Apr 17–Apr 24.
When to plant oregano in zone 7b
Zones 7a and 7b share the same average frost dates, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. It needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Feb 13–Feb 20 |
|---|---|
| Direct sow / transplant outside | Apr 17–Apr 24 |
| Estimated harvest | Jul 6–Jul 13 (~80 days after transplanting) |
Spacing: 4 per square foot (square-foot-gardening spacing). Mature height: 1-1.5 ft.
Plant alongside it in zone 7b
These go outside within two weeks of oregano in zone 7b, so one planting day can cover them.

Oregano is a low, spreading perennial in the mint family, and one of the more forgiving herbs you can grow. It performs better in lean, dry soil than in rich, well-watered beds.
How oregano fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Oregano needs about 80 days from transplant to first harvest.
