Stenospermation andreanum Engl.

• Genus: Stenospermation
• Botanical Background: Described by the renowned botanist Adolf Engler, the species carries historical significance in botanical exploration and nomenclature from the 19th century.

• Geographical Range: Indigenous to tropical areas of South America
• Environment: Thrives in warm, humid conditions with filtered light; preferring well-draining, organically rich soils common in its native forest habitat

Leaves

• Medium to large
• Typically heart-shaped with a glossy texture and prominent venation
• Deep green color with subtle patterns

Inflorescence (Spadix & Spathe)

• Modest, greenish or cream-colored spathe that encloses a compact spadix
• Not known for a strong scent
• Adapted for specific pollinators in its ecosystem

Growth Habit

• Terrestrial
• Growing from a rhizomatous base that gradually forms clumps,

Light Requirements

• Bright, indirect light; similar to the dappled sunlight conditions of a forest understory.

Watering & Humidity

• Consistent moisture; with a preference for high humidity however, the plant does best when the soil is kept moist but not waterlogged.
• Optimal temperature range is between 65°F and 80°F (18°C to 27°C)
• Balanced, diluted fertilizer applied during the growing season will support vigorous growth

Soil & Potting Mix

• A well-aerated, peat-based mix enriched with organic matter is ideal
• Container that ensures excellent drainage

Temperature & Fertilizer

• Thrives between 65–85°F (18–29°C)
• Balanced liquid fertilizer at half-strength every 4–6 weeks during active growth

Division

• Rhizome division during repotting

Stem Cuttings (if applicable)

• Rhizome division to ensure that each division has healthy shoots

Seeds

• Seeds can be used, they are less common due to slower germination rates and the more efficient propagation via division

Typical Issues

• May attract spider mites and mealybugs
• Poor drainage can lead to root rot

Treatment Recommendations

• Organic insecticidal soaps or targeted organic insecticides work well for pest control
• Ensure proper watering habits and adequate airflow

• Notable for its understated yet attractive inflorescence and its representation of the botanical diversity found in tropical understories
• Collectorsm prize for its distinctive leaf structure and its ability to adapt to indoor cultivation under controlled conditions

Wild Population Status

• Not currently classified as endangered; ongoing habitat loss in tropical regions is a concern

Market Availability

• Moderately available through specialty nurseries
• May require some searching or importing for those outside its native range
