About Dracaena 'Lemon Lime'

Dracaena fragrans 'Lemon Lime' · also called Lemon Lime Dracaena, Lemon Lime Corn Plant · houseplant

Dracaena 'Lemon Lime' is a striking foliage houseplant grown for its sword-shaped leaves striped in chartreuse and dark green. It thrives in bright indirect light, infrequent watering, and average warmth, making it forgiving for beginners. Note: the ASPCA lists Dracaena fragrans as toxic to cats and dogs, so keep it away from pets.

Cold limit: USDA 10-12 (frost-tender; grown as a houseplant elsewhere) (18-26°C)

Watch for — Drooping or curling leaves: Often from underwatering or cold drafts. Check that the soil isn't bone-dry and move the plant away from cold windows, AC vents, and heaters.

What dracaena 'lemon lime''s hardiness rating actually means

Dracaena 'Lemon Lime' 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 10-12 (frost-tender; 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). Dracaena 'Lemon Lime' has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

Concretely, for dracaena 'lemon lime' 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 dracaena 'lemon lime' 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 dracaena 'lemon lime' can be outside. US growers can check USDA zones; UK growers should use the RHS hardiness ratings, which match the H1c figure above.
