Peperomia rotundifolia 'Trailing Jade' is a dainty trailing peperomia with tiny, round, button-like jade-green leaves on thread-fine stems.

ASPCA-listed as non-toxic to cats and dogs.

What peperomia rotundifolia 'trailing jade''s hardiness rating actually means

Peperomia rotundifolia 'Trailing Jade' 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 (indoor in most US homes) — 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). Peperomia rotundifolia 'Trailing Jade' has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for peperomia rotundifolia 'trailing jade' 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 peperomia rotundifolia 'trailing jade' 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 peperomia rotundifolia 'trailing jade' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1b figure above.
