What echeveria 'perle von nurnberg''s hardiness rating actually means

Echeveria 'Perle von Nurnberg' 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 zones 9b-11 (frost-tender); grow as an indoor or container plant elsewhere and protect below about 4C (40F). — the zones where it can be left outdoors year-round.

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.
