About Caladium Gingerland

Caladium 'Gingerland' · also called Gingerland caladium · tropical

Caladium 'Gingerland' is a fancy-leaf caladium with strappy grey-green leaves splashed with maroon flecks and bordered in deep green. Grown from a tuber, it pushes out vivid paper-thin foliage through the warm months, then dies back to rest. It suits warm, humid spots in bright indirect light and is popular for containers, borders, and shaded patios.

Cold limit: USDA 9-11 (lift or overwinter tubers below zone 9) · RHS H1b (21-29°C)

Watch for — Sudden dieback: Often natural dormancy or cold exposure below ~18°C. Reduce water and store the tuber warm and dry until spring.

What caladium gingerland's hardiness rating actually means

Caladium Gingerland 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 9-11 (lift or overwinter tubers below zone 9) — 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). Caladium Gingerland has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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