About Campos Porto Fuchsia

Fuchsia campos-portoi · also called Campos Porto Fuchsia, Compos-Porto Fuchsia · flowering

Fuchsia campos-portoi is a cold-hardy Brazilian species native to the rocky campos rupestres of the Itatiaia massif in Minas Gerais and Rio de Janeiro states, growing at 2,100–2,550 m elevation. It is regarded as one of the most heat- and cold-tolerant Fuchsia species, with top growth dying back around -6°C but roots hardy to at least -18°C. Plant in fertile, moist, well-drained soil in sun or partial shade; it is an excellent choice for milder UK gardens where most fuchsias would fail. Fuchsia is listed as non-toxic to cats, dogs, and horses by the ASPCA.

Cold limit: USDA 7b-10 · RHS H4 (-18 to 25°C (root hardy; tops die back below -6°C))
