About Alocasia Frydek (Green Velvet)

Alocasia micholitziana 'Frydek' · also called Green Velvet Alocasia, Frydek · tropical

Alocasia Frydek is a striking tropical aroid prized for arrow-shaped, deep-green velvety leaves laced with bright white veins. Its one defining need is consistently high humidity, ideally 50-60% or more, paired with warmth and bright indirect light. Get the air moist enough and it rewards you; let it dry and chill, and it sulks into dormancy.

Cold limit: 18-27°C

Watch for — Yellowing lower leaves and root rot: Usually overwatering or soggy, cold soil. Let the top third dry between waterings, ensure free drainage, and cut back hard in winter.

What alocasia frydek (green velvet)'s hardiness rating actually means

Alocasia Frydek (Green Velvet) 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 not formally rated (treat as tender) — 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). Alocasia Frydek (Green Velvet) has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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 alocasia frydek (green velvet) 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 alocasia frydek (green velvet) can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1b figure above.
