About Variegated Japanese Spurge

Pachysandra terminalis 'Variegata' · also called Variegated Japanese Spurge, Variegated Pachysandra · flowering

A shade-tolerant evergreen groundcover with attractive white-edged, toothed leaves that brighten dark corners. Less vigorous than the green-leaved species, making it ideal for smaller spaces or mixed shade plantings. White flower spikes emerge in early spring. Best suited to partial shade where leaf variegation remains crisp and attractive.

Cold limit: USDA 4-9 · RHS H7 (-34°C to 30°C)

Watch for — Marginal leaf scorch: White leaf margins brown at the tips in conditions of drought, high heat, direct sun, or salt spray. Ensure consistent moisture, position in shade, and avoid salt-based de-icing products near plantings in winter.

What variegated japanese spurge's hardiness rating actually means

Minimum temperature — and what happens below it

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

Concretely, for variegated japanese spurge 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 variegated japanese spurge go outside or overwinter — and where?

Plant it out within USDA 4-9 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 variegated japanese spurge can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H7 figure above.
