About Variegated Greater Periwinkle

Vinca major 'Variegata' · also called Variegated Greater Periwinkle, Variegated Periwinkle · flowering

A trailing evergreen sub-shrub bearing eye-catching leaves edged in creamy-white, offset by violet-blue spring flowers. Widely grown in containers and hanging baskets for its bright variegation. Slightly less vigorous than the straight species, making it somewhat easier to manage. Hardy to USDA zone 7.

Cold limit: USDA 7-11 · RHS H5 (-10°C to 30°C)

What variegated greater periwinkle's hardiness rating actually means

Yes — variegated greater periwinkle is genuinely cold hardy. Rated RHS H5 and USDA 7-11, 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 7-11 — 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 about −15 to −10 °C. Variegated Greater Periwinkle is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for variegated greater periwinkle 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 variegated greater periwinkle go outside or overwinter — and where?

Plant it out within USDA 7-11 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 variegated greater periwinkle can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H5 figure above.

Frost protection for borderline variegated greater periwinkle

Variegated Greater Periwinkle is right on a hardiness edge in many gardens, so if you are pushing it, these measures buy it the margin it needs:

At the cold edge of its range, mulch the root zone in late autumn to buffer the deepest freezes.
Protect container specimens — pots freeze through far faster than open ground, costing roughly a zone of hardiness.
Shelter new growth from late spring frosts with fleece if a hard night is forecast.
