Levisticum officinale
When to plant lovage in zone 5b
Zones 5a and 5b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Lovage needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Mar 22–Mar 29 |
|---|---|
| Direct sow / transplant outside | May 17–May 24 |
| Estimated harvest | Aug 15–Aug 22 (~90 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 4-6.5 ft.

Lovage tastes like celery turned up several notches, and it grows like it means it: a single plant can reach 6 feet tall and just as wide once established, which is a strange thing to learn about an herb most people have never grown. One plant is enough for a household that uses it in stocks, soups, and salads.
How lovage fits zone 5's season
Zone 5b's frost-free window runs about 148 days, from May 10 to October 5. Lovage needs about 90 days from transplant to first harvest.
