Amorphophallus paeoniifolius (Dennst.) Nicolson

• Genus: Amorphophallus
• Botanical Background: Described by Johann Carl Dennstedt in the 18th century, with taxonomist N. Nicolson later refining its classification. It belongs to a genus renowned for its striking inflorescence and its ecological roles in its native environments.

• Geographical Range: Native to Southeast Asia, including countries like India, Sri Lanka, and the Philippines; it can also be found in parts of Indonesia and Malaysia
• Environment: Thriving in tropical climates, this plant is typically found in humid, warm environments with well-draining, fertile soils; it prefers shady, forested areas but can tolerate some sun. It is most often seen at low to mid-elevations in its native habitat

Leaves

• large and palmate, resembling an umbrella in shape
• With dark green color and a glossy texture
• Can grow up to 2 meters long
• Their impressive size adds to the plant's ornamental appeal

Inflorescence (Spadix & Spathe)

• Consists of a large spadix surrounded by a dark purple spathe
• The flower itself is large, with a potent odor, often likened to rotting meat, which attracts pollinators like carrion beetles and flies

Growth Habit

• A terrestrial plant that grows from a large tuber
• Dies back to the ground after flowering and then regrows from the tuber the following year

Light Requirements

• Thrives in bright, indirect light but can tolerate some direct sunlight
• In cultivation, providing dappled shade simulates its natural conditions

Watering & Humidity

• Keep the soil moist but not waterlogged
• High humidity is essential
• Regular misting may be needed to maintain ideal conditions
• During the dormant period, reduce watering
  

Soil & Potting Mix

• A well-draining potting mix, such as one made for aroids or a mixture of peat, perlite, and pine bark
• Ensures the plant’s roots do not rot while maintaining moisture retention

Temperature & Fertilizer

• Between 25-30°C (77-86°F) and can handle occasional cooler temperatures
• Balanced liquid fertilizer every 4-6 weeks

Division and Stem Cuttings

• Division of the tuber
• Each piece should contain at least one bud or eye to ensure successful growth

Seeds

• Less commonly used
• Seeds must be fresh and can be slow to germinate, requiring consistent warmth and moisture

Typical Issues

• Aphids, scale, and mealybugs
• Root rot

Treatment Recommendations

• Organic insecticidal soap or neem oil can be effective for pest control
  
• Ensure the plant is in well-drained soil
• Fungicides may be necessary for severe fungal infections
  

• The tuber is widely used in Asian cuisine; rich in starch and is typically boiled or fried
• In traditional medicine, it is believed to have various health benefits, including aiding digestion
• Unique and large foliage, combined with its exotic inflorescence, makes it a striking ornamental
• Enthusiasts prize it for both its beauty and the novelty of its unusual flowering

Wild Population Status

• While not currently listed as endangered, habitat loss in parts of Southeast Asia could impact wild populations
• Conservation efforts focus on sustainable farming and habitat protection

Market Availability

• Commonly available in horticultural markets, especially in tropical regions
• May be harder to find in colder climates, where its cultivation is less common
