Plant Profile: Aglaonema commutatum

This herbaceous perennial is frequently cultivated as an indoor plant. It is an evergreen tropical shrub that can grow up to 1.5 feet tall, characterized by its upright and bushy form. Its appearance is similar to that of dumb cane (Dieffenbachia). The plant features dark green, lance-shaped leaves that measure between 4 to 8 inches in length and 2 to 3 inches in width, adorned with attractive silver-gray blotches on its upright stems. While it rarely flowers indoors, it may produce a white spadix surrounded by a green spathe in late summer or early fall, followed by clusters of red berries. This plant thrives in diffuse sunlight or bright indirect light and prefers high humidity, although it can adapt to drier air. It is essential to keep the potting mix moist from spring through fall, and while it does not require a winter dormancy, it benefits from reduced watering during the colder months.

Valued for its upright green leaves, which are variegated with yellow or cream, this plant may become leggy over time as the stem elongates and bends. To promote healthy growth, it is advisable to remove any flowers and fruits. It serves as an excellent choice for low-light environments typical of many homes and can also function as a filler plant or low hedge in warmer climates. The plant prefers low to medium light, moist soil, and moderate humidity, but it does not tolerate consistently wet soil or direct sunlight and may face some pest and disease challenges.

In terms of pests and diseases, there are no significant issues, but it is important to monitor for aphids, mealybugs, spider mites, and scale. Overwatering can lead to root rot, so it is crucial to allow the soil to dry out between waterings and to avoid using cold water. Leaves may brown in excessively dry air or drafty conditions. The plant is sensitive to cold temperatures and thrives best in a daytime temperature range of 70°F to 80°F.

**Quick Identification Tips:**
This plant can be distinguished from Dieffenbachia by its characteristic 5 to 8 main lateral veins. It differs from A. nitidum due to its predominant green coloration and the presence of yellow or cream variegation in A. commutatum.
