About Yellow Latan Palm

Latania verschaffeltii · also called Yellow Latan Palm, Verschaffelt's Latan Palm · tropical

Yellow Latan Palm from Rodrigues Island in the Mascarenes is distinguished by bold fan fronds with bright yellow-orange midribs and petioles, especially vivid on young plants. It demands intense sun and fast-draining soil. A conservation-listed species in the wild, it is a coveted collector's palm for tropical gardens.

Cold limit: USDA 10b-12 · RHS H1a (16–38°C)

What yellow latan palm's hardiness rating actually means

Yellow Latan 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 10b-12 — 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 above about 15 °C (warm, never cold). Yellow Latan Palm has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for yellow latan 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 yellow latan 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 yellow latan palm can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1a figure above.
