About Tulip Anthurium

Anthurium andraeanum 'Lumina' · also called Tulip-flowered Anthurium · flowering

Tulip Anthurium is a compact flamingo-flower cultivar whose upward-cupped spathes resemble a half-open tulip rather than the usual flat heart shape. A tidy, free-flowering aroid for bright rooms, it shares standard anthurium needs: warmth, high humidity, bright filtered light and a chunky, fast-draining mix kept lightly and evenly moist.

Cold limit: USDA 11-12 (indoor in most US homes) · RHS H1b (18-29°C)

Watch for — Spathes losing their cupped shape: Often low humidity or heat stress. Raise humidity and keep temperatures steady to maintain the tulip form.

What tulip anthurium's hardiness rating actually means

Tulip Anthurium 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.

Minimum temperature — and what happens below it

Minimum survivable temperature is roughly about 10 °C (sustained cold below this is damaging). Tulip Anthurium has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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

Tulip Anthurium hardiness — frequently asked questions

Is tulip anthurium cold hardy?

Tulip Anthurium 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. Tulip Anthurium 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 tulip anthurium can survive?

What hardiness zone is tulip anthurium?

Tulip Anthurium 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 tulip anthurium survive winter outside?

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.

What happens to tulip anthurium 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. 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.
