Chinese evergreen
Chinese evergreen (Aglaonema commutatum) evolved in the humid forests of the Philippines and Sulawesi, under the filtered light of the understory. This explains its tolerance of partial shade and sensitivity to cold, wet potting mix.
Leaf and stem structure
The leaves are large and elongated, forming a crown at the top of a short stem. In young plants, the stem is almost hidden by foliage; in mature plants, it becomes visible and bears scars from fallen leaves.
Aglaonemas as a group have oval, elliptical, lance-shaped, or heart-shaped leaves. Color depends on the form or cultivar: green, dark green, or silver, with spots or stripes along the veins.
- a short stem that becomes more visible with age
- large, elongated leaves
- variegation that becomes more pronounced in good indirect light
Origin and natural conditions
The species is native to the Philippines and Sulawesi. Reference descriptions associate the genus Aglaonema with the humid tropical forests of Southeast Asia, where the plants grow in the understory and do not receive direct sun throughout the day.
This origin explains the shade tolerance of green-leaved forms, but it does not mean that every Chinese evergreen grows well in a dark corner. Variegated leaves need more indirect light; otherwise, their pattern becomes less distinct.
| In nature | Indoors |
|---|---|
| filtered light in the understory | a spot without direct midday sun |
| a humid tropical environment | consistent moisture without standing water |
| loose natural substrate | a well-drained aroid potting mix |
Light and placement
Green-leaved forms tolerate shade better than variegated ones. Variegated plants need bright indirect light: direct sun can damage the leaves, while deep shade slows growth.
- a bright spot behind a sheer curtain or near a window without direct sun
- partial shade for forms with predominantly green leaves
- protection from cold drafts in winter
If new leaves are smaller or their pattern fades, the plant is most likely not getting enough light. Move it gradually: the effects of a sudden change in conditions often show up on young leaves.
Watering and potting mix
In spring and summer, water the potting mix when the top layer dries out. Reduce watering in winter: after the top layer has dried, let the mix stay on the drier side for a short time so the roots do not remain constantly wet.
The mix should be loose and well-drained. Sources recommend a mix of leaf mold, peat, and sand with added charcoal and well-rotted manure for Chinese evergreen; the main requirements are air around the roots and no standing water.

- drainage holes in the pot

Flowers and fruit
As a member of Araceae, the plant produces not a single “flower” but an inflorescence—a spadix with a spathe. Inflorescences in the genus Aglaonema are described as emerging from the leaf axils at the top of the shoot.
Oval berries, often brightly colored, may form after flowering. Indoors, Chinese evergreen is usually grown for its foliage, so the inflorescences are not its main ornamental feature.
Indoors, the dormant period is described as lasting from September to February. During this time, the plant needs less water and should not be kept in the cold: winter temperatures must not fall below +16 °C.
Propagation and repotting
Chinese evergreen is propagated vegetatively by cuttings or division, and can also be grown from seed. Indoors, division and cuttings are used more often because they make it easier to preserve the traits of a particular form.
- taking stem or tip cuttings
- dividing the plant during repotting
- sowing seeds after the fruit ripens
Repot in spring. Young plants are repotted annually; mature plants every 4-5 years, provided the potting mix has not compacted and the roots have not filled the pot.
Common problems
The most common problems are caused not by the plant being “fussy,” but by unsuitable light, watering, and temperatures. Constantly wet potting mix increases the risk of root rot, while cold winter drafts quickly damage the foliage.
- yellowing leaves caused by overwatering or cold
- loss of variegation due to insufficient light
- pest damage on weakened plants
Pests reported on aglaonemas include spider mites, whiteflies, aphids, thrips, scale insects, and mealybugs. Checking the undersides of the leaves helps detect an infestation before the plant loses much foliage.

Care
Chinese evergreen is well adapted to indirect light and consistent warmth. The main risks indoors are cold, waterlogged potting mix, and a location that is too dark for variegated forms.
- Light
- Provide partial shade or indirect light. Green-leaved forms tolerate shade; variegated forms need brighter indirect light without direct sun.
- Temperature
- Keep at +20…+25 °C. This is the range for the growing season. In winter, keep the temperature at or above +16 °C and protect the plant from drafts.
- Watering
- Water when the top layer dries out. In spring and summer, water when the top layer dries out. Reduce watering in winter so the potting mix does not stay constantly wet.
- Soil
- Use a loose, well-drained potting mix. A mix based on leaf mold, peat, and sand with added charcoal is suitable; avoid letting water collect around the roots.
- Feeding
- Feed twice a month during the growing season. Alternate mineral and organic fertilizers during active growth. Reduce feeding during dormancy.
- Leaves
- Wipe dust off the leaves. The large leaves quickly collect dust, which reduces their ability to use light. Clean them with a soft, damp cloth.
- Repotting
- Repot in spring. Repot young plants annually and mature plants every 4-5 years, or when the potting mix has compacted and the roots need more room.

Chinese evergreen (Aglaonema commutatum) belongs to the family Araceae. It is a member of the genus Aglaonema, which consists of evergreen herbaceous plants and subshrubs with short stems that become more visible with age, and large, elongated leaves.
The species is native to the Philippines and Sulawesi. The genus typically grows in humid tropical forests, where light is filtered and the substrate stays moist but not waterlogged.
The inflorescence has the typical aroid structure: a spadix with a spathe, rather than a single flower. Aglaonemas produce oval berries containing seeds.
How it differs from similar plants
ZZ plant Zamioculcas zamiifolia
- The ZZ plant is easily distinguished by its compound leaves, which resemble stems, while Chinese evergreen has large, elongated leaves.
Peace lily Spathiphyllum wallisii
- Peace lily is recognizable by the white spathe around its spadix and a clump of basal leaves without a visible stem, while Chinese evergreen is mainly distinguished by its large, elongated leaves.
Anthurium Anthurium andraeanum
- Anthurium needs bright indirect light, while Chinese evergreen tolerates partial shade and indirect light.
Frequently asked questions
- Can I keep Chinese evergreen in shade?
- Yes, but partial shade is better than complete darkness. Variegated forms lose the definition of their leaf patterns in deep shade.
- Why are the leaves turning yellow?
- This is most often caused by overwatering, a cold location, or drafts. Check whether the top layer of potting mix has time to dry out.
- Is Chinese evergreen dangerous to cats and dogs?
- Yes, the plant is toxic to cats and dogs. Do not place it where a pet can chew the leaves.
- How often should I repot Chinese evergreen?
- Repot young plants every spring and mature plants every 4-5 years. Repotting is also needed if the potting mix has compacted.
- How do I propagate Chinese evergreen?
- The plant is propagated by cuttings, division, and seed. Indoors, cuttings or division are used most often.
