About Dracaena 'Song of India'

Dracaena reflexa 'Song of India' · also called Song of India, Pleomele · houseplant

Song of India is a slow-growing, easy-care Dracaena with arching canes of glossy, lime-and-cream striped leaves. It wants bright indirect light, fluoride-free watering once the top of the pot dries, and warm, draught-free rooms. The ASPCA lists Dracaena as toxic (mildly so) to cats and dogs, so keep it out of reach.

Cold limit: USDA 10–12 (grown as a houseplant elsewhere) (18–27°C (tolerates 12–32°C))

Watch for — Yellowing leaves: Most often overwatering and soggy soil, but also cold water or temperature stress. Let the top of the pot dry before watering and keep it away from cold draughts.

What dracaena 'song of india''s hardiness rating actually means

Dracaena 'Song of India' 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 (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 'Song of India' has no frost tolerance at all — it is an indoor plant in any climate with a real winter.

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