About Pineapple Mint

Mentha suaveolens 'Variegata' · also called Pineapple Mint, Variegated Apple Mint · herb

Pineapple mint is a vigorous, spreading perennial herb with cream-edged, softly hairy leaves carrying a distinct fruity-mint fragrance. Grow in moist, moderately fertile soil in full sun to partial shade. Containment is essential — rhizomes spread aggressively. Best harvested from late spring through early autumn. Excellent for teas, fruit salads, and garnishes.

Cold limit: USDA 5–9 · RHS H5 (10–26°C)

What pineapple mint's hardiness rating actually means

Yes — pineapple mint is genuinely cold hardy. Rated RHS H5 and USDA 5–9, it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H5 means: Hardy in most of the UK and in cold winters. On the US scale that maps to USDA 5–9 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −15 to −10 °C. Pineapple Mint is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for pineapple mint as it gets too cold:

It tolerates winter lows to about −15 to −10 °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 pineapple mint go outside or overwinter — and where?

Plant it out within USDA 5–9 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 pineapple mint can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H5 figure above.
