About Neglected Pink

Dianthus pavonius · also called Neglected Pink, Peacock-eye Pink · flowering

Native to sunny grasslands and rocky slopes in the southwestern Alps and Pyrenees up to 2,900 m elevation, Dianthus pavonius (syn. D. neglectus) is a compact, cushion-forming alpine pink that demands full sun and sharply drained, gritty, neutral to slightly alkaline soil. Its fragrant single flowers are deep rose-pink with a distinctive buff-coloured reverse to the petals, appearing in summer, making it a jewel for rock gardens and scree. The single most critical care point is ensuring perfect drainage year-round, as even brief waterlogging at the crown will kill the plant. According to the ASPCA, Dianthus (Pinks) are toxic to cats and dogs.

Cold limit: USDA 5-8 · RHS H7 (-25 to 25°C)

What neglected pink's hardiness rating actually means

Yes — neglected pink is genuinely cold hardy. Rated RHS H7 and USDA 5-8, 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 5-8 — 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. Neglected Pink is built for winter — once established it takes hard frost and snow in its stride.

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

Plant it out within USDA 5-8 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 neglected pink can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H7 figure above.
