Amorphophallus haematospadix Hook.f.

• Genus: Amorphophallus
• Botanical Background: Described by botanist Joseph Dalton Hooker in the 19th century. The genus Amorphophallus has been studied for its remarkable inflorescences, which are often used to study pollination strategies.

• Geographical Range: Native to tropical Southeast Asia, with a particular prevalence in Malaysia and Indonesia, where it thrives in moist, lowland environments
• Environment: Naturally grows in tropical rainforests with high humidity levels, rich soil, and a stable warm climate; it requires moist conditions to thrive, often being found in shaded areas under taller canopy trees.

Leaves

• Large, typically lanceolate or palmate, with a deep green coloration
• They emerge after the plant's flowering cycle and have a prominent, glossy texture

Inflorescence (Spadix & Spathe)

• Consists of a deep red spathe that surrounds a central spadix, which is smaller compared to other species in the genus
• The spathe can reach up to 30 cm in height and is known for a pungent odor used to attract pollinators, particularly carrion-feeding insects

Growth Habit

• A terrestrial plant that produces a large, swollen tuber from which the leaves and inflorescences emerge
• Does not climb or grow epiphytically and has a relatively short flowering season

Light Requirements

• Prefers low to moderate light, ideally bright, indirect light
• Does not tolerate direct sunlight for extended periods as it can cause leaf scorch

Watering & Humidity

• Requires consistently moist soil, especially during its growing season.
• Thrives in environments with high humidity
• Regular misting or a humidity tray can help replicate its native habitat

Soil & Potting Mix

• Well-draining, rich organic soil is recommended 
• A mix of potting soil with added perlite or sand works well
• Prefers soil with slightly acidic to neutral pH

Temperature & Fertilizer

• Grows best in temperatures ranging from 25°C to 30°C (77°F to 86°F)
• Balanced fertilizer applied during the growing season, typically once a month, with a focus on nitrogen to encourage leaf growth

Division and Stem Cuttings

• Division of the tuber
• Ensure each division has at least one growing eye or bud

Seeds

• Not commonly used due to germination rates typically low
• Require warm conditions to germinate; seeds should be planted immediately after harvesting

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
  

• Famous for its large and unpleasant-smelling flower
• Valued for its unique inflorescence and is often sought after by collectors of unusual plants
• Its dramatic flower, though short-lived, makes for an eye-catching display in appropriate settings

Wild Population Status

• There are no major conservation concerns currently noted for Amorphophallus haematospadix, but habitat destruction in Southeast Asia poses a potential threat to its wild populations

Market Availability

• Not commonly found in mainstream markets but may be available through specialty nurseries or aroid enthusiasts
• Considered rare in cultivation, especially outside its native range
