About Creeping Globe Daisy

Globularia repens · also called Creeping Globe Daisy, Dwarf Globe Daisy · flowering

Creeping Globe Daisy is an exceptionally compact, mat-forming evergreen perennial from the Pyrenees and southern Alps, growing even tighter and flatter than its relative G. cordifolia. Tiny spoon-shaped dark leaves form a dense mossy carpet, smothered in miniature blue-purple globe flowers in late spring. Perfect for rock gardens, scree, and troughs.

Cold limit: USDA 4-7 · RHS H7 (-25°C to 20°C)

Watch for — Crown rot in winter wet: The tightest enemy of this species. A single extended period of waterlogging in winter can kill the entire mat. In the UK and similar climates, protect with a sheet of glass overhead while keeping sides open for air circulation.

What creeping globe daisy's hardiness rating actually means

Yes — creeping globe daisy is genuinely cold hardy. Rated RHS H7 and USDA 4-7, 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 4-7 — 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. Creeping Globe Daisy is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for creeping globe daisy 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 creeping globe daisy go outside or overwinter — and where?

Plant it out within USDA 4-7 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 creeping globe daisy can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H7 figure above.
