About Lucky bamboo

Dracaena sanderiana · also called ribbon plant, curly bamboo · houseplant

Lucky bamboo is not a bamboo at all but a Dracaena from Central Africa, sold as upright canes in water or in shallow soil. It tolerates low light and is one of the easiest plants to keep alive for years. Mildly toxic to cats and dogs.

Despite the name it is not a bamboo but Dracaena sanderiana, an Asparagaceae shrub native to West/West-Central tropical Africa (Cameroon, the Congo region) into north-east Angola, where it grows in the dappled understory of warm, humid tropical forest.

A slow-growing woody perennial that can be kept compact indoors for years; it is toxic to cats and dogs (saponins), causing vomiting, hypersalivation, depression and dilated pupils in cats per the ASPCA.

Cold limit: USDA 10-11 (indoor-only) · RHS H1b (18-32°C)

What lucky bamboo's hardiness rating actually means

Lucky bamboo 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 10-11 (indoor-only) — 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 °C (sustained cold below this is damaging). Lucky bamboo has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for lucky bamboo 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 lucky bamboo 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 lucky bamboo can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1b figure above.

Lucky bamboo hardiness — frequently asked questions

Is lucky bamboo cold hardy?

Lucky bamboo 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. Lucky bamboo can only live outside year-round in genuinely frost-free climates (roughly USDA 10-11 (indoor-only)); everywhere else it is a houseplant that summers out at most.

What is the minimum temperature lucky bamboo can survive?

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

What hardiness zone is lucky bamboo?

Lucky bamboo is rated USDA 10-11 (indoor-only) and RHS H1b — Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season.

Can lucky bamboo 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 lucky bamboo 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. 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.
