About Aglaonema Burmese Evergreen

Aglaonema brevispathum · also called Burmese Evergreen, Short-Spathed Aglaonema · houseplant

Aglaonema brevispathum is a species Chinese evergreen from Southeast Asia, with elongated lance-shaped green leaves marked by a fine silver-green midrib and speckling. Less hybridised than modern cultivars, it is robust and shade-tolerant, thriving in warm, humid, low-light spots. A clean, architectural foliage plant for beginners who want an authentic species form.

Cold limit: USDA 10-12 (grown as a houseplant in most US and UK homes) · RHS H1b (18-28°C)

Watch for — Yellowing leaves: Typically overwatering or cold exposure. Allow the surface to dry between waterings and keep warm.

What aglaonema burmese evergreen's hardiness rating actually means

Aglaonema Burmese Evergreen 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 as a houseplant in most US and UK 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 Burmese Evergreen has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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