Guzmania dissitiflora · also called Scattered-flower Guzmania, Spreading Guzmania · tropical

Guzmania dissitiflora is a Central American epiphytic bromeliad native to Colombia, Costa Rica, and Panama, typically found growing on mossy tree branches in humid cloud forests. It forms a glossy-leaved rosette that funnels water to a central cup and produces a branched inflorescence bearing scattered orange-red bracts and white tubular flowers. The most important care fact is keeping the central cup topped up with rainwater or filtered water at all times. Bromeliads of this genus are considered non-toxic to cats and dogs.

What scattered-flower guzmania's hardiness rating actually means

Scattered-flower Guzmania 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 10-12 (indoor in most climates) — 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). Scattered-flower Guzmania has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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