About Alocasia Bambino Arrow

Alocasia × amazonica 'Bambino Arrow' · also called Bambino Arrow alocasia, compact African mask · tropical

Alocasia 'Bambino Arrow' is a dwarf African mask hybrid with narrow, arrow-shaped dark green leaves veined in silvery white and flushed purple underneath. Its compact size suits small bright spots and terrarium-style growing. Like all amazonica types it grows from a corm and demands warmth, high humidity, and a careful watering rhythm to avoid rot.

Cold limit: USDA 10-11 (indoor in most US homes) · RHS H1b (18-28°C)

Watch for — Sudden leaf loss / dormancy: Cold, overwatering, or stress can send the corm dormant. Keep warm, water sparingly, and the corm will reshoot if it stays firm.

What alocasia bambino arrow's hardiness rating actually means

Alocasia Bambino Arrow 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 10-11 (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 10 °C (sustained cold below this is damaging). Alocasia Bambino Arrow has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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