About Lovage

Levisticum officinale · also called Garden Lovage, Maggi Herb · herb

Lovage is a tall, vigorous perennial herb whose hollow stems and glossy leaves taste intensely of celery and yeasty stock, earning it the nickname Maggi herb. A single plant feeds a kitchen all summer and dies back over winter to return each spring. It likes rich, moist soil and sun to part shade and grows surprisingly large.

Cold limit: USDA 4-8 · RHS H7 (10-26°C)

What lovage's hardiness rating actually means

Yes — lovage is genuinely cold hardy. Rated RHS H7 and USDA 4-8, it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H7 means: Hardy in the severest European continental winters. On the US scale that maps to USDA 4-8 — the zones where it can be left outdoors year-round.

New to these scales? The USDA hardiness zone map explained covers how the zone numbers work, and you can find your own zone with the zone finder.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly below about −20 °C. Lovage is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for lovage as it gets too cold:

It tolerates winter lows to about −20 °C once established.
Below its rated zone, the visible damage is browned or blackened top growth and, in the worst case, a killed crown or root.
First-year, newly planted, or container-grown specimens are noticeably less hardy than established garden plants — the roots are exposed.

Can lovage go outside or overwinter — and where?

Plant it out within USDA 4-8 and it overwinters with little or no help.
It does not want to come indoors — a warm winter room actually weakens a hardy plant by denying it dormancy.
The real risks in its range are waterlogging, wind-rock on young plants, and a late hard frost on new growth — not ordinary winter cold.

Work back from your local frost dates with the frost-date calculator: the last spring frost and first autumn frost are what really decide when lovage can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H7 figure above.
