Amorphophallus maximus (Engl.) N.E.Br.

• Genus: Amorphophallus 
• Botanical Background: Described by prominent botanists Adolf Engler and N.E. Brown, Amorphophallus maximus has been a subject of botanical interest for its unique inflorescence structure and growth form.

• Geographical Range: Indigenous to tropical lowland forests of Africa, where conditions support a diverse range of aroid species.
• Environment: Thrives in warm, humid climates with well-drained soils; it typically grows in areas that experience consistent moisture and moderate seasonal variation.

Leaves

• Large, compound
• Glossy texture and pronounced lobing
• The leaves display varied green hues and a robust structure

Inflorescence (Spadix & Spathe)

• It produces an imposing inflorescence with a dark, robust spadix paired with a contrasting, pale spathe
• May emit a subtle scent

Growth Habit

• Growing from a tuberous rhizome; terrestrial
• Characterized by a seasonal cycle that includes a dormant period after the flowering phase

Light Requirements

• Prefers bright, indirect light to mimic the dappled sunlight of its native understory habitat

Watering & Humidity

• Regular watering is essential
• Maintaining high humidity
• Soil should remain moist but not waterlogged

Soil & Potting Mix

• A loose, well-draining soil mix rich in organic matter is ideal
• Containers with ample drainage ensure that excess moisture does not accumulate

Temperature & Fertilizer

• Optimal temperatures range from 70°F to 90°F
• Balanced fertilizer applied monthly during the growing season supports healthy development

Division and Cuttings

• Most effective propagation technique is through division of the tubers or rhizome
• Ensuring each section has sufficient buds for new growth

Seeds

• Less common due to low germination rates and specific viability requirements

Typical Issues

• Spider mites and mealybugs
• Root rot can occur if the plant is overwatered or planted in poorly draining soil

Treatment Recommendations

• Use insecticidal soap for pest control or neem oil for an organic solution
• Treat with a fungicide, and ensure proper drainage in the pot

• Local folklore in parts of Africa sometimes highlights the species for its dramatic appearance
• Ecologically, its large inflorescence plays a role in attracting specialized pollinators

• Highly prized by collectors
• Admired for its rare and eye-catching bloom as well as its impressive foliage structure

Wild Population Status

• While not currently classified as endangered, habitat loss remains a potential threat to wild populations

Market Availability

• Generally rare in cultivation and is sought after by aroid collectors
• Occasionally available through specialty nurseries
