Aglaonema simplex Blume

• Genus: Aglaonema
• Botanical Background: Described by Carl Ludwig Blume in the 19th century, the species was identified during his extensive botanical surveys in the Indonesian archipelago. Blume played a key role in cataloging many tropical Asian aroids.

• Geographical Range: Native to Thailand, Peninsular Malaysia, Borneo, and surrounding islands, A. simplex is widespread across lowland and hill forests.
• Environment: Thrives in moist, shaded forest understories, typically growing in well-drained humus-rich soils with high humidity. It is tolerant of fluctuating rainfall and moderate elevation.

Leaves

• Elliptic-lanceolate, typically 10–25 cm long
• Smooth, leathery texture
• Uniformly green with subtle venation and may have a slightly glossy surface

Inflorescence (Spadix & Spathe)

• Consists of a pale green spathe enclosing a short, erect spadix
• Generally inconspicuous and may emit a faint odor to attract pollinators such as beetles

Growth Habit

• A. simplex is a terrestrial herb with a clumping growth pattern
• It arises from a short rhizome and tends to form dense groundcover colonies

Light Requirements

• Medium to low indirect light
• Avoid direct sunlight, which can scorch the foliage

Watering & Humidity

• Water regularly but allow the top inch of soil to dry out between waterings
• High humidity (above 60%) encourages optimal growth

Soil & Potting Mix

• A well-draining mix rich in organic matter (peat-based or aroid-specific blends)
• Containers should allow for drainage

Temperature & Fertilizer

• Ideal temperature range is 18–28°C (64–82°F)
• Feed with a diluted balanced liquid fertilizer every 4–6 weeks during active growth

Division

• Division of rhizomes or basal offsets

Stem Cuttings (if applicable)

• Stem cuttings can root in water or moist substrate

Seeds

• Rare in cultivation
• Seeds are viable but require warm, humid conditions and patience, with germination taking several weeks

Typical Issues

• Spider mites, aphids, and mealybugs
• Overwatering can lead to root rot

Treatment Recommendations

• Use neem oil or insecticidal soap for pests
• Prevent root rot with proper drainage and cautious watering
• Isolate affected plants

• A. simplex is sometimes used in traditional landscaping across Asia for shade gardens
• Its tolerance of poor light makes it ideal for offices or dim indoor spaces

• Appreciated for its simplicity, ease of care, and lush green foliage
• Favored by beginners and collectors looking to create dense, tropical displays

Wild Population Status

• Not listed as threatened, though habitat loss in parts of Southeast Asia may impact local populations

Market Availability

• Moderately available through specialty nurseries and online retailers
• Not as common as variegated Aglaonema cultivars but sought after for naturalistic plantings
