About Pothos-leaf Labisia

Labisia pothoina · also called Pothos-leaf Labisia, Pothoina Labisia · tropical

Pothos-leaf Labisia is a rare tropical understory herb from Southeast Asian rainforests, named for its broader leaves that somewhat resemble those of pothos. Less commonly cultivated than Labisia pumila, it shares the genus's requirement for deep shade, very high humidity, and warm, stable temperatures. Grown as a collector's foliage plant in terrariums and paludariums.

Cold limit: USDA 11–12 · RHS H1a (22–30°C)

What pothos-leaf labisia's hardiness rating actually means

Pothos-leaf Labisia 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 11–12 — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

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

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