About Pink Rock Jasmine

Androsace carnea · also called Pink Rock Jasmine, Flesh-pink Androsace · flowering

Pink Rock Jasmine is a delicate cushion-forming alpine from the Pyrenees and Alps, producing tight mounds of narrow grey-green leaves adorned with clusters of pale to deep pink flowers with yellow eyes in late spring. A prized specimen for alpine troughs, tufa, and rock gardens, it demands excellent drainage, full sun, and moisture-free winters.

Cold limit: USDA 3–6 · RHS H7 (-20°C to 18°C)

Watch for — Winter cushion rot: The most frequent cause of plant loss. Water collecting in the hairy rosettes during cold, damp winters causes botrytis and bacterial rot. Grow in an alpine house through winter or protect with a glass pane to shed rain while maintaining airflow.

What pink rock jasmine's hardiness rating actually means

Yes — pink rock jasmine is genuinely cold hardy. Rated RHS H7 and USDA 3–6, 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 3–6 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

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

Concretely, for pink rock jasmine 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 pink rock jasmine go outside or overwinter — and where?

Plant it out within USDA 3–6 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 pink rock jasmine can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H7 figure above.
