“Dracaena vs Chinese evergreen” usually means corn plant against aglaonema, two foliage plants widely grown in homes and offices (Clemson, NC State). They are not closely related. Corn plant is Dracaena fragrans, an African member of the asparagus family (Asparagaceae). Chinese evergreen is Aglaonema, an aroid from tropical Asia and New Guinea, in the same family as peace lily and philodendron (NC State Extension).
Both tolerate indoor light well below a sunny window, and both dislike cold and soggy soil. The differences that matter are height, how little light each will accept, fluoride and cold sensitivity, and which toxin each contains.
How to tell them apart
Corn plant. NC State describes a tall, unbranched stem with many broad, strap-like leaves, like a stalk of corn. The leaves spiral up the stem, clasp it at the base and grow up to 45 cm (18 in) long and 7.5–13 cm (3–5 in) wide. They droop as they lengthen. Most plants sold have white, yellow or lime-green stripes running along the leaf, such as ‘Massangeana’ with its central yellow band (Clemson Extension).
NC State lists Dracaena deremensis as a former name, so ‘Janet Craig’ and ‘Warneckii’ now sit under D. fragrans as well. ‘Janet Craig’ has dark, glossy green leaves; ‘Warneckii’ has white-striped leaves (Clemson).
Chinese evergreen. NC State describes an erect, bushy plant with lance-shaped leaves 10–30 cm (4–12 in) long and 5–10 cm (2–4 in) wide. Each leaf sits on a distinct stalk, sometimes white. Leaves are often banded or spotted with silver, grey, pink or red along the veins. NC State notes it resembles dumb cane (Dieffenbachia), but has only five to eight main side veins.
In short: a cane with long, striped, strap leaves is a dracaena. A low clump of broader, patterned leaves on stalks is an aglaonema.

| Humidity | Brown tips in dry air (NC State, Clemson) | Tolerates low humidity; prefers moderate (Clemson) |
| Temperature | Thrives at 21–27 °C (70–80 °F); keep above 10 °C (50 °F) (NC State) | Best at 20–27 °C (68–80 °F); chilling injury below 10 °C (50 °F) (Clemson) |
| Special sensitivity | Fluoride (Clemson) | Cold and chilling (Clemson, UF/IFAS) |

Light: aglaonema goes darker
Both are sold as low-light plants, but Chinese evergreen copes with less. University of Missouri Extension says Aglaonema modestum can tolerate light as low as 10 foot-candles. Clemson says solid green aglaonema cultivars grow in low light. Illinois Extension suggests shadow-less light, such as a north window.
Colour changes that. Clemson says variegated aglaonemas need low to moderate light. UF/IFAS adds that high-colour (pink and red) selections need bright, indirect light to keep their colour.
Corn plant tolerates low light, and Missouri Extension notes dracaenas also do well in medium light. Clemson says most grow best in bright, indirect light. When a dim plant moves somewhere brighter, its new leaves are thicker and growth speeds up. NC State warns the leaves narrow if light is too low. Clemson names ‘Warneckii’ as one of the best variegated plants for low light.
Neither wants direct sun. NC State says it can burn corn plant foliage, and Clemson links round dry patches and streaks to excess sun. UF/IFAS says aglaonema scorches in too sunny a spot.
Watering and humidity
Both need a pot with drainage holes. Clemson names root rot from a slow-draining mix or overwatering as a problem for both.
Corn plant. NC State says keep the soil moist in the growing season and cut back in winter. Clemson is more specific: let the plant dry slightly, wait until the surface is dry to the touch, then water thoroughly with water that is not cold. Brown leaf tips often mean dry air. NC State suggests a humidifier in heated winter rooms.
Chinese evergreen. Clemson says keep the soil moist but not wet, and water once the top 2.5–5 cm (1–2 in) is dry. Push two fingers into the mix: dry means water, cold and damp means wait. NC State suggests reducing water in winter. Clemson says most grow well at the low to moderate humidity of an average house.
Fluoride: the dracaena-specific problem
Clemson notes that dracaena is very sensitive to fluoride. Symptoms are yellow tips or margins, or dead, scorched areas. Its advice is to avoid potting mixes with a high proportion of perlite, keep soil pH at 6.0–6.5, and avoid fertilisers containing superphosphate. Clemson also notes that heavy feeding can burn or yellow leaf tips. Our dracaena fluoride toxicity guide covers diagnosis.
Aglaonema has its own sensitivity: cold. Clemson says it is sensitive to chilling below 10 °C (50 °F). UF/IFAS says temperatures below 7 °C (45 °F) can injure the foliage. Keep it away from winter windows and air-conditioning vents.
Size, pruning and propagation
Corn plant becomes a floor plant. NC State gives 91 cm to 4.4 m (3 to 14.5 ft) as its height range. Clemson says dracaenas are easy to keep shorter: cut a long, bare stem at the height you want and new leaves soon appear. The cut top can be rooted as a cutting or air layered.
Chinese evergreen stays at table or low floor height. NC State says it gets leggy with age. Clemson says that when the lower stem becomes bare, you can remove the top and root it. Division and air layering also work (Clemson).
Pet safety
Neither is safe for a pet that chews leaves.
- Corn plant. The ASPCA lists it as toxic to dogs, cats and horses. The toxic principle is saponins. Listed signs are vomiting (occasionally with blood), depression, loss of appetite, drooling and, in cats, dilated pupils.
- Chinese evergreen. The ASPCA lists it as toxic to dogs, cats and horses because of insoluble calcium oxalates. Listed signs are mouth pain and swelling, drooling, vomiting and difficulty swallowing.
For non-toxic options, see our pet-safe plants guide.
Which should you choose?
- Dim office or north room, no window nearby: a green or silver Chinese evergreen.
- You want height in a corner: corn plant, which becomes a tall cane.
- Desk, shelf or low table: Chinese evergreen.
- Bright room with filtered light: either, but give pink and red aglaonemas the brightest indirect spot.
- Draughty or cool spot in winter: neither is ideal. NC State says keep corn plant above 10 °C (50 °F), and Clemson says aglaonema tolerates no lower than 13 °C (55 °F).
- A past dracaena kept getting yellow, scorched tips: check the fluoride causes Clemson lists, or choose aglaonema instead.
For full care of the aglaonema, see our Chinese evergreen care guide. For more dim-room picks, see plants for desks and low-light offices.
