About Epipremnum amplissimum 'Silver Streak'

Epipremnum amplissimum 'Silver Streak' · also called Silver Streak Pothos, Streaked Epipremnum · houseplant

Epipremnum amplissimum 'Silver Streak' is a climbing pothos relative grown for long, narrow leaves streaked with silvery variegation. It is an easy-going aroid: give it bright indirect light, let the top of the soil dry between waterings, and provide a moss pole to encourage larger, more dramatic foliage. Like all pothos it is toxic to pets if chewed.

Cold limit: USDA 11-12 (indoor in most US and UK homes) · RHS H1b (18-29°C)

What epipremnum amplissimum 'silver streak''s hardiness rating actually means

Epipremnum amplissimum 'Silver Streak' 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 11-12 (indoor in most US and UK homes) — 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). Epipremnum amplissimum 'Silver Streak' has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for epipremnum amplissimum 'silver streak' 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 epipremnum amplissimum 'silver streak' 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.
