About Green-Spotted Neoregelia

Neoregelia chlorosticta · also called Green-Spotted Neoregelia, Green-Spotted Bromeliad · tropical

A medium Brazilian tank bromeliad recognized by its strap-shaped green leaves marked with contrasting lighter green spots or blotches — the source of the epithet 'chlorosticta' (green-spotted). The center blushes red at flowering. Hardy for a bromeliad, tolerating slightly lower humidity than most relatives. Pet-safe and ornamentally distinctive.

Cold limit: USDA 10–12 · RHS H1b (15–30°C)

What green-spotted neoregelia's hardiness rating actually means

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

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

Green-Spotted Neoregelia hardiness — frequently asked questions

Is green-spotted neoregelia cold hardy?

Green-Spotted Neoregelia 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.
