About Campfire Crassula (Red Pagoda)

Crassula capitella 'Campfire' · also called Campfire crassula, Red pagoda · houseplant

Campfire crassula is a low, mat-forming succulent whose propeller-shaped leaves blaze fiery red in bright sun and cool weather, fading to lime-green in shade. Give it strong light, gritty fast-draining soil, and sparse water. ASPCA does not list it individually, but the Crassula genus includes toxic jade, so treat as mildly toxic to pets.

Cold limit: USDA USDA 9b-11 (hardy to roughly 25-30 F / -3 to -1 C); grow as a houseplant or move indoors where frost occurs (18-24 C ideal; survives brief dips to about 10 C)

Watch for — Stretching and loss of red colour (etiolation): In too little light the plant turns green, stems elongate, and leaves space out. This is the single most common indoor complaint. Move it to direct sun or add a grow light; the fiery colour returns with strong light and cooler temperatures.

What campfire crassula (red pagoda)'s hardiness rating actually means

Campfire Crassula (Red Pagoda) 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 USDA 9b-11 (hardy to roughly 25-30 F / -3 to -1 C); grow as a houseplant or move indoors where frost occurs — 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). Campfire Crassula (Red Pagoda) has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for campfire crassula (red pagoda) 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 campfire crassula (red pagoda) 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 campfire crassula (red pagoda) can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1b figure above.
