About Zebra Plant Dania

Aphelandra squarrosa 'Dania' · also called Dania zebra plant · tropical

Aphelandra squarrosa 'Dania' is a compact zebra plant grown for dramatic dark green leaves laced with bold ivory veins and, when conditions suit, a cone of bright yellow bracts. A demanding Brazilian tropical, it wants warmth, high humidity, bright indirect light and steady moisture, and is quick to drop leaves if it dries out, chills or sits in dry air.

Cold limit: USDA 11-12 (indoor in most US homes) · RHS H1b (18-26°C)

Watch for — Leaf drop: The classic zebra-plant complaint, caused by dryness at the roots, low humidity, cold draughts or temperature swings. Keep moisture, warmth and humidity steady.

What zebra plant dania's hardiness rating actually means

Zebra Plant Dania 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 11-12 (indoor in most US homes) — 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 10 °C (sustained cold below this is damaging). Zebra Plant Dania has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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

Zebra Plant Dania hardiness — frequently asked questions

Is zebra plant dania cold hardy?

Zebra Plant Dania 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. Indoor-only in almost every home. Zebra Plant Dania can only live outside year-round in genuinely frost-free climates (roughly USDA 11-12 (indoor in most US homes)); everywhere else it is a houseplant that summers out at most.

What is the minimum temperature zebra plant dania can survive?

What hardiness zone is zebra plant dania?

Zebra Plant Dania is rated USDA 11-12 (indoor in most US homes) and RHS H1b — Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season.

Can zebra plant dania survive winter outside?

It will never overwinter outside in a temperate climate; the indoors is its winter home, full stop.

What happens to zebra plant dania below its minimum temperature?

Below about about 10 °C, growth stalls and the leaves start to show cold stress — dark, water-soaked, or yellowing patches.
