About Zebra Basket Vine

Aeschynanthus marmoratus · also called Zebra Basket Vine, Marbled Lipstick Plant · houseplant

Zebra Basket Vine is a trailing gesneriad grown primarily for its dramatic foliage — dark green leaves dramatically marbled with lighter green and purple-flushed undersides. Its tubular green-and-brown flowers are subtle but interesting. Like other Aeschynanthus, it is ASPCA non-toxic, making it a pet-safe choice.

Cold limit: USDA 10-12 (indoor-only in most homes) · RHS H1c (18-27°C)

Watch for — Yellowing leaves: Can result from overwatering, cold draughts, or nutrient deficiency. Check soil moisture and temperature, and resume feeding in the growing season if none of those are the cause.

What zebra basket vine's hardiness rating actually means

Zebra Basket Vine 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 homes) — 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). Zebra Basket Vine has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for zebra basket vine 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 zebra basket vine 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 zebra basket vine can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1c figure above.
