When to plant hyssop in zone 7b
Zones 7a and 7b 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. Hyssop tolerates either.
| Start indoors | Feb 13–Feb 20 |
|---|---|
| Direct sow / transplant outside | Apr 17–Apr 24 |
| Estimated harvest | Jul 11–Jul 18 (~85 days after planting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 1.5-2 ft.
Hyssop is a woody, semi-evergreen perennial in the mint family with a strong, minty-bitter flavor that's historically shown up more in liqueurs like Chartreuse and in potpourri than in everyday cooking. It's grown as much for its spikes of blue flowers and the bees they attract as for any culinary use.
How hyssop fits zone 7's season
Zone 7b's frost-free window runs about 198 days, from April 10 to October 25. Hyssop needs about 85 days from sowing to first harvest.
