About Kalanchoe Eriophylla

Kalanchoe eriophylla · also called snow white panda plant, woolly kalanchoe · houseplant

Kalanchoe eriophylla is a low Madagascan succulent densely covered in white woolly hairs that give the whole plant a frosted, silvery look, earning the name snow white panda plant. It forms spreading mats of fuzzy, silver leaves and bears pink to lavender flowers. Compact and slow, it needs bright light and dry conditions, and like all Kalanchoe it is toxic to pets.

Cold limit: USDA 10-11 (indoor in most US homes) · RHS H1c (15-27°C)

Watch for — Loss of silvery felting: Low light and handling reduce the dense white coating that gives the plant its frosted look. Increase light and minimise touching the leaves to preserve the wool.

What kalanchoe eriophylla's hardiness rating actually means

Kalanchoe Eriophylla 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 10-11 (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 5 °C (and never frost). Kalanchoe Eriophylla has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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

Kalanchoe Eriophylla hardiness — frequently asked questions

Is kalanchoe eriophylla cold hardy?

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

What is the minimum temperature kalanchoe eriophylla can survive?

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

What hardiness zone is kalanchoe eriophylla?

Kalanchoe Eriophylla is rated USDA 10-11 (indoor in most US homes) and RHS H1c — Warm-temperate — can summer outdoors but must come in well before the first frost.

Can kalanchoe eriophylla survive winter outside?

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.

What happens to kalanchoe eriophylla below its minimum temperature?

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.
