About Vriesea carinata

Vriesea carinata · also called lobster claws, painted feather vriesea · tropical

Vriesea carinata, the lobster claws bromeliad, is a small Brazilian tank species with soft pale-green leaves and a flattened sword-shaped inflorescence boldly marked red, yellow and green. Compact and free-flowering, it is an epiphyte watered through its cup, enjoys warm humid rooms and bright filtered light, and is non-toxic to pets.

Cold limit: USDA 10-11 (indoor in most US and UK homes) · RHS H1b (18-27°C)

Watch for — Cup rot: Stagnant or cold water in the tank rots the crown; flush and refill the cup regularly with tepid water.

What vriesea carinata's hardiness rating actually means

Vriesea carinata 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 10-11 (indoor in most US and UK 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). Vriesea carinata has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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

Vriesea carinata hardiness — frequently asked questions

Is vriesea carinata cold hardy?

Vriesea carinata 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. Vriesea carinata can only live outside year-round in genuinely frost-free climates (roughly USDA 10-11 (indoor in most US and UK homes)); everywhere else it is a houseplant that summers out at most.

What is the minimum temperature vriesea carinata can survive?

What hardiness zone is vriesea carinata?

Vriesea carinata is rated USDA 10-11 (indoor in most US and UK homes) and RHS H1b — Sub-tropical — a normal warm home is fine, but it cannot go outside in a cool season.

Can vriesea carinata 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 vriesea carinata 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.
