About Meebold's Lagenandra

Lagenandra meeboldii · also called Meebold's Lagenandra, Pink Lagenandra · tropical

Lagenandra meeboldii is a striking semi-aquatic aroid from South India and Sri Lanka, known for its pink-to-reddish, broadly ovate leaves with a metallic sheen. Grown in paludariums, aquariums, or moist terrariums, it prefers stable warmth and high humidity. Toxic to pets as an aroid containing calcium oxalates.

Cold limit: USDA 11–12 (indoor or paludarium only) · RHS H1b (23–30°C)

What meebold's lagenandra's hardiness rating actually means

Meebold's Lagenandra 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 11–12 (indoor or paludarium only) — 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). Meebold's Lagenandra has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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