About Terap

Artocarpus elasticus · also called Terap, Bendo · tropical

Terap is a towering rainforest tree from maritime Southeast Asia in the Moraceae (breadfruit) family. It thrives in humid tropical conditions with full sun and rich, free-draining soil. Juvenile plants produce enormous lobed leaves. Fruit resembles a small breadfruit with sweet, aromatic pulp. Best suited to frost-free tropical gardens or very large containers.

Cold limit: USDA 10b–12 · RHS H1a (21–35°C)

Watch for — Leaf scorch: Brown, crispy leaf margins appear when humidity drops sharply or cold dry winds blow. Increase ambient humidity and protect from desiccating winds with windbreaks or companion planting.

What terap's hardiness rating actually means

Terap 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). Terap has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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

Terap hardiness — frequently asked questions

Is terap cold hardy?

Terap 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. Terap 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 terap can survive?

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

What hardiness zone is terap?

Terap is rated USDA 10b–12 and RHS H1a — Tropical — needs a heated room or greenhouse; no frost tolerance whatsoever.

Can terap survive winter outside?

What happens to terap below its minimum temperature?

Below about above about 15 °C, growth stalls and the leaves start to show cold stress — dark, water-soaked, or yellowing patches.
