About Neoregelia 'Charm'

Neoregelia 'Charm' · also called charm neoregelia, pink neoregelia charm · tropical

Neoregelia 'Charm' is a colourful hybrid tank bromeliad forming a flat, open rosette whose leaves flush pink and rose, brightest toward the centre as flowering nears. Unlike Guzmanias the show comes from leaf colour, not a tall spike; small blue-violet flowers nestle low in the water-filled cup. It needs bright light to hold its colour and clumps readily from offsets.

Cold limit: USDA 10-11 (indoor in most US homes) · RHS H1c (18-27°C)

What neoregelia 'charm''s hardiness rating actually means

Neoregelia 'Charm' 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 H1c means: Warm-temperate — can summer outdoors but must come in well before the first frost. On the US scale that maps to USDA 10-11 (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 5 °C (and never frost). Neoregelia 'Charm' has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for neoregelia 'charm' as it gets too cold:

Below about about 5 °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 neoregelia 'charm' go outside or overwinter — and where?

It can holiday outdoors in summer once nights are reliably above 5 °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 neoregelia 'charm' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1c figure above.
