About Chilean Wine Palm

Jubaea chilensis · also called Chilean wine palm, honey palm · tropical

The Chilean wine palm is a massive, long-lived feather palm from central Chile, famous for an enormously thick grey trunk and a dense crown of stiff fronds. Remarkably cold-hardy for a palm, it is very slow and drought-tolerant once established. It bears small edible coconut-like fruits and needs sun, deep free-draining soil and patience.

Cold limit: USDA 8b-11 (hardy outdoors in mild UK/US coastal areas; tolerates light frost) · RHS H4 (10-28°C)

Watch for — Root rot in winter wet: Cold, waterlogged soil is the main risk. Ensure deep, sharp drainage and ease off watering in winter.

What chilean wine palm's hardiness rating actually means

Yes — chilean wine palm is genuinely cold hardy. Rated RHS H4 and USDA 8b-11 (hardy outdoors in mild UK/US coastal areas; tolerates light frost), it lives outdoors all year and needs winter cold rather than protection from it. Its RHS rating of H4 means: Hardy in an average winter across much of the temperate world. On the US scale that maps to USDA 8b-11 (hardy outdoors in mild UK/US coastal areas; tolerates light frost) — 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 −10 to −5 °C. Chilean Wine Palm is built for winter — once established it takes hard frost and snow in its stride.

Concretely, for chilean wine palm 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 chilean wine palm go outside or overwinter — and where?

Plant it out within USDA 8b-11 (hardy outdoors in mild UK/US coastal areas; tolerates light frost) 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 chilean wine palm can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H4 figure above.
