About Ardisia Elliptica

Ardisia elliptica · also called shoebutton ardisia, duck's eye ardisia · houseplant

Ardisia elliptica, shoebutton ardisia, is a fast, shade-tolerant evergreen shrub from coastal Asia with glossy elliptic leaves, pink flowers, and red berries ripening glossy black. Indoors it wants bright indirect light, even moisture, and warmth. It is highly invasive outdoors in warm regions, and its berries and leaves can cause gastrointestinal upset in pets.

Cold limit: USDA 10-12 outdoors; houseplant elsewhere · RHS H1b (18-29°C)

What ardisia elliptica's hardiness rating actually means

Ardisia Elliptica 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 10-12 outdoors; houseplant elsewhere — 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). Ardisia Elliptica has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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

Ardisia Elliptica hardiness — frequently asked questions

Is ardisia elliptica cold hardy?

Ardisia Elliptica 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. Ardisia Elliptica can only live outside year-round in genuinely frost-free climates (roughly USDA 10-12 outdoors; houseplant elsewhere); everywhere else it is a houseplant that summers out at most.

What is the minimum temperature ardisia elliptica can survive?

What hardiness zone is ardisia elliptica?

Ardisia Elliptica is rated USDA 10-12 outdoors; houseplant elsewhere and RHS H1b — Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season.

Can ardisia elliptica 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 ardisia elliptica 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.
