About Ficus Tineke (variegated rubber plant)

Ficus elastica 'Tineke' · also called variegated rubber plant, variegated rubber tree · houseplant

Ficus 'Tineke' is a variegated rubber plant, a glossy tropical tree splashed cream, grey-green and pink. Grown indoors as an upright statement plant, it wants bright indirect light to hold its colour, watering when the topsoil dries, and warmth. The ASPCA lists Ficus as toxic, so it is best treated as mildly toxic around pets.

Cold limit: USDA 10-12 (indoor-only in most climates) (15-29°C)

Watch for — Leaf drop after moving: Like fiddle-leaf figs, rubber plants sulk when relocated or after a draught or cold snap. Give it a stable spot and 3-4 weeks to settle.

What ficus tineke (variegated rubber plant)'s hardiness rating actually means

Ficus Tineke (variegated rubber plant) 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 10-12 (indoor-only in most climates) — the zones where it can be left outdoors year-round.

Minimum temperature — and what happens below it

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

Concretely, for ficus tineke (variegated rubber plant) 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 ficus tineke (variegated rubber plant) 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 ficus tineke (variegated rubber plant) can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1c figure above.
