About Begonia 'Cracklin' Rosie'

Begonia 'Cracklin' Rosie' · also called Cracklin' Rosie begonia, Cracklin' Rose begonia · houseplant

Begonia 'Cracklin' Rosie' is a cane (angel-wing) begonia hybrid grown for dramatic fluted bronze leaves spotted with pink over a deep-red reverse. Give it bright indirect light, an airy peat-perlite mix, and water once the top inch dries. It is toxic to cats and dogs per the ASPCA.

Cold limit: USDA 10-11 (frost-tender; grown as a houseplant elsewhere) (16-21°C)

Watch for — Crispy leaf edges: Brown, dry leaf margins signal air that is too dry or too hot. Raise humidity, keep it away from radiators and cold drafts, and maintain steady watering.

What begonia 'cracklin' rosie''s hardiness rating actually means

Begonia 'Cracklin' Rosie' 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 (frost-tender; grown as a houseplant elsewhere) — the zones where it can be left outdoors year-round.

New to these scales? The USDA hardiness zone map explained covers how the zone numbers work, and you can find your own zone with the zone finder.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about 5 °C (and never frost). Begonia 'Cracklin' Rosie' has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for begonia 'cracklin' rosie' 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 begonia 'cracklin' rosie' 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 begonia 'cracklin' rosie' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1c figure above.
