Amorphophallus teuszii (Engl.) Mottet

• Genus: Amorphophallus
• Botanical Background: Described by Adolf Engler and later revised by Mottet, Amorphophallus teuszii has been the subject of botanical studies that highlight its unique characteristics.

• Geographical Range: Native to select regions in tropical Africa.
• Environment: Thrives in environments with high humidity, rich organic soils, and dappled sunlight and commonly associated with the understorey of tropical rainforests where moisture and decomposing leaf litter support its growth.

Leaves

• Large, compound leaves that are pinnately divided
• Broad with a rich green coloration and a textured surface

Inflorescence (Spadix & Spathe)

• Distinctive inflorescence consisting of a central spadix surrounded by a sizable spathe
• Spathe can range in hues from greenish to purplish
• Plays a key role in attracting specific pollinators through visual and olfactory cues

Growth Habit

• Terrestrial with an underground tuber
• Growth habit supports its seasonal appearance and enables it to survive periods of dormancy

Light Requirements

• Bright but indirect light
• Direct, harsh sunlight should be avoided to prevent leaf scorch

Watering & Humidity

• Maintain consistently moist soil while ensuring proper drainage
• Benefits from high humidity levels, mimicking its native tropical conditions

Soil & Potting Mix

• A well-draining, nutrient-rich potting mix enriched with organic matter
• Container that allows for ample root expansion and proper drainage

Temperature & Fertilizer

• Temperatures range between 70°F and 85°F
• Balanced fertilizer applied during the growing season, should be used sparingly to avoid nutrient burn

Division 

• Common method of propagation is through the division of its tubers
• This technique is effective once the plant has established a significant underground mass
  

Seeds

• Viability is often low and germination may require specific conditions that closely resemble its natural tropical environment

Typical Issues

• Aphids, mealybugs, and spider mites
• Fungal issues like root rot can occur if the soil remains too wet

Treatment Recommendations

• Insecticidal soap or neem oil
• Ensure adequate air circulation around the plant
• Well-draining substrate and avoiding overwatering

• Rare occurrence and unique flowering structure add to its allure in specialized collections
• Prize for its uncommon appearance and impressive foliage

• Unusual inflorescence makes it a conversation piece in tropical and exotic plant collections

Wild Population Status

• Due to habitat destruction and limited natural distribution, it is considered rare in the wild

Market Availability

• Not widely available in mainstream horticultural markets
• Usually reserved for advanced collectors and specialized botanical garden
