Chinese evergreen, Aglaonema commutatum, is native specifically to the Philippines and northeastern Sulawesi in Indonesia, despite the common English name suggesting a Chinese origin — a naming mismatch shared with several other houseplants whose common names reflect where they became popular in cultivation rather than where they actually evolved. The broader genus Aglaonema, which includes around twenty-six recognized species along with many cultivated hybrids, is native more generally across the tropical and subtropical regions of Southeast Asia and New Guinea. In the wild, the species grows in the deeply shaded understorey of tropical forests, typically receiving very low light levels for most of the day, an ecological detail that directly explains the plant's now-famous tolerance for dim indoor corners where few other patterned-leaf houseplants can hold their color and vigor.

The plant belongs to the arum family, Araceae, and its close visual resemblance to Dieffenbachia (dumb cane) is well documented and occasionally causes confusion between the two; botanically, Aglaonema can be distinguished from Dieffenbachia by having only five to eight main lateral leaf veins, a subtler structural difference than most casual observers would think to check but a reliable one for anyone comparing the two plants side by side. One of the species' informal common names, "poison dart plant," sounds considerably more dramatic than its actual toxicity profile warrants — like most aroids, Chinese evergreen contains insoluble calcium oxalate crystals throughout its tissue, which cause oral irritation, mouth and throat swelling, and gastrointestinal upset if chewed or ingested, placing it in the same general toxicity category as peace lily, philodendron, and ZZ plant, rather than anything approaching the potency the "poison dart" name might imply.
