About Philodendron Rugosum (Pigskin)

Philodendron rugosum · also called Pigskin Philodendron, Pig Skin Philodendron · tropical

Philodendron rugosum, the Pigskin Philodendron, is a rare aroid from Ecuador's cloud forests prized for thick, leathery, wrinkled leaves. Give it bright indirect light, evenly moist but fast-draining soil, warmth, and high humidity, plus a moss pole to climb. Toxic to cats and dogs per the ASPCA, so keep it out of reach.

Cold limit: USDA USDA zones 10-12 (outdoors); grown as a houseplant elsewhere. (18-27°C (tolerates 13-32°C))

Watch for — Yellowing leaves: Often overwatering or, if lower leaves only, natural ageing. Check that soil is not staying wet and that the pot drains; cold drafts below 13°C (55°F) can also yellow and drop leaves.

What philodendron rugosum (pigskin)'s hardiness rating actually means

Philodendron Rugosum (Pigskin) 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 USDA zones 10-12 (outdoors); grown as a houseplant elsewhere. — 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). Philodendron Rugosum (Pigskin) has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for philodendron rugosum (pigskin) 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 philodendron rugosum (pigskin) 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 philodendron rugosum (pigskin) can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1c figure above.
