About Pacaya Palm

Chamaedorea tepejilote · also called Pacaya Palm, Tepejilote · edible

A multi-stemmed understorey palm native to the tropical forests of southern Mexico and Central America, widely cultivated in Guatemala and El Salvador for its edible male flower buds, known as 'pacaya', which are a traditional delicacy eaten raw, fried, or in stews. It forms cane-like stems with long, pinnate fronds and prefers a warm, humid, shaded environment. Being a tropical species it requires frost-free conditions and is best kept indoors or in a heated greenhouse in the UK and most of the US. Chamaedorea tepejilote is considered non-toxic to cats and dogs, consistent with the non-toxic ASPCA genus listing for Chamaedorea.

Cold limit: USDA 10b-12 · RHS H1b (18 to 32°C)

What pacaya palm's hardiness rating actually means

Pacaya 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 H1b means: Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season. On the US scale that maps to USDA 10b-12 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about 10 °C (sustained cold below this is damaging). Pacaya Palm has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for pacaya palm as it gets too cold:

Below about about 10 °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 pacaya palm go outside or overwinter — and where?

It can holiday outdoors in summer once nights are reliably above 10 °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 pacaya palm can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1b figure above.

Pacaya Palm hardiness — frequently asked questions

Is pacaya palm cold hardy?

Pacaya 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. Indoor-only in almost every home. Pacaya Palm can only live outside year-round in genuinely frost-free climates (roughly USDA 10b-12); everywhere else it is a houseplant that summers out at most.

What is the minimum temperature pacaya palm can survive?

Minimum survivable temperature is roughly about 10 °C (sustained cold below this is damaging). Pacaya Palm has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

What hardiness zone is pacaya palm?

Pacaya Palm is rated USDA 10b-12 and RHS H1b — Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season.

Can pacaya palm survive winter outside?

It can holiday outdoors in summer once nights are reliably above 10 °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.

What happens to pacaya palm below its minimum temperature?

Below about about 10 °C, growth stalls and the leaves start to show cold stress — dark, water-soaked, or yellowing patches.
