About Panda Face Ginger

Asarum maximum · also called Panda Face Ginger, Panda Face Wild Ginger · houseplant

Asarum maximum is a slow-growing, evergreen woodland perennial prized for its bold, heart-shaped leaves—often marbled silver—and distinctive black-and-white panda-faced flowers hidden beneath the foliage in spring. It thrives in deep shade with humus-rich, consistently moist soil and suits containers indoors or shaded border plantings outdoors in zones 6–9.

Cold limit: USDA 6-9 · RHS H4 (5–24°C)

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about −10 to −5 °C. Panda Face Ginger is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for panda face ginger as it gets too cold:

It tolerates winter lows to about −10 to −5 °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 panda face ginger go outside or overwinter — and where?

Plant it out within USDA 6-9 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 panda face ginger can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H4 figure above.
