About Traveller's Palm

Ravenala madagascariensis · also called traveller's palm, traveller's tree · tropical

Ravenala madagascariensis is a monotypic tree-like monocot in the Strelitziaceae family, native to open and disturbed humid forests of Madagascar, where it forms spectacular fan-shaped crowns of enormous banana-like leaves arranged in a single, flat plane oriented east-to-west. The common name 'traveller's palm' derives from the rainwater that accumulates at the base of the leaf sheaths — reportedly a source of emergency drinking water. In the UK and most of the US it must be grown in a heated glasshouse or large conservatory; in USDA zones 10–11 it can be grown outdoors as a statement landscape specimen. The most important care fact is full sun and generous space — this plant eventually reaches 10–15 m outdoors. Ravenala madagascariensis is considered non-toxic to cats, dogs, and horses based on available safety data.

Cold limit: USDA 10-11 · RHS H1a (16–35 °C)

What traveller's palm's hardiness rating actually means

Traveller's Palm is not cold hardy. It is a tropical houseplant that dies if it is left out through frost — there is no zone where it overwinters outdoors in a UK or cold-US climate. Its RHS rating of H1a means: Tropical — needs a heated room or greenhouse; no frost tolerance whatsoever. On the US scale that maps to USDA 10-11 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly above about 15 °C (warm, never cold). Traveller's Palm has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for traveller's palm as it gets too cold:

Below about above about 15 °C, growth stalls and the leaves start to show cold stress — dark, water-soaked, or yellowing patches.
A single light frost blackens the foliage; a hard freeze kills the whole plant, roots included, and it does not recover.
Even a cold, draughty windowsill or an unheated porch in winter can be enough to damage it permanently.

Can traveller's palm go outside or overwinter — and where?

It can holiday outdoors in summer once nights are reliably above above 15 °C, in shade or dappled light, hardened off gradually.
Bring it back indoors well before the first autumn frost — do not wait for a frost warning, move it when nights drop toward 10-12 °C.
It will never overwinter outside in a temperate climate; the indoors is its winter home, full stop.

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 traveller's palm can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1a figure above.
