Amorphophallus stuhlmannii (Engl.) Engl. & Gehrm.

• Genus: Amorphophallus
• Botanical Background: Described by renowned botanists Adolf Engler and Gehrm, reflecting a rich history of botanical exploration in Africa and historical records and herbarium specimens have since contributed to its studied profile in specialized botanical circles.

• Geographical Range: Indigenous to parts of tropical Africa, with its occurrence documented in regions that include Angola and nearby areas.
• Environment: Thrives in the understories of moist, shaded tropical forests where humus-rich, well-draining soils prevail.

Leaves

• Large, compound leaves that are deeply lobed
• Glossy texture and vibrant green coloration

Inflorescence (Spadix & Spathe)

• Slender spadix enclosed by a bold spathe 
• Often shows greenish to purplish-brown hues
• Not heavily scented, the structure is well-adapted to attract specific pollinators

Growth Habit

• Grows from a tuber and typically produces a single prominent inflorescence per cycle

Light Requirements

• Bright indirect light is ideal

Watering & Humidity

• Maintain consistent moisture, especially during the active growing season
• High humidity is beneficial

Soil & Potting Mix

• A rich, organic, and well-draining soil mix
• Blend that holds moisture without becoming waterlogged

Temperature & Fertilizer

• Temperatures range from 70°F to 85°F (21°C to 29°C)
• Balanced, diluted fertilizer applied during the growing season

Division and Cuttings

• Careful division of the tubers during the plant’s dormant phase
• Ensures that each section retains sufficient energy to thrive independently

Seeds

• Seed production is possible, it is not the primary mode of propagation due to the typically low germination rate

Typical Issues

• Aphids, mealybugs, and occasional fungal infections

Treatment Recommendations

• Organic insecticidal soaps
• Cultural practices that improve air circulation and drainage
• Careful application of fungicides

• Celebrated for its dramatic flowering display
• Unique appearance has also led to various local folklore associations

• Value for its rarity and its unusual inflorescence
• Distinctive aesthetic makes it a prized addition to specialized tropical plant collections and botanical gardens

Wild Population Status

• Comprehensive conservation assessments are limited
• Habitat disruption due to deforestation and land-use changes poses potential risks

Market Availability

• Relatively rare in cultivation
• Sought after by dedicated collectors
