About Aglaonema Stripes

Aglaonema 'Stripes' · also called Striped Chinese Evergreen, Stripes Aglaonema · houseplant

Aglaonema 'Stripes' is a Chinese evergreen cultivar with long, narrow leaves laced by feathery silvery-white veins running parallel from the midrib, giving a pinstripe effect. It shares the genus's easygoing nature, thriving in low light and tolerating missed waterings. Its elegant linear foliage and upright habit make it a refined, low-fuss houseplant.

Cold limit: USDA 10-12 (grown indoors in most US homes) · RHS H1b (18-27°C)

What aglaonema stripes's hardiness rating actually means

Aglaonema Stripes 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 (grown indoors 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). Aglaonema Stripes has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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