Amorphophallus bangkokensis Gagnep.

• Genus: Amorphophallus
• Botanical Background: Described by the French botanist Gagnepain, the species has been studied in the context of Southeast Asian flora. 

• Geographical Range: Indigenous to tropical regions of Southeast Asia, with recorded occurrences in areas surrounding Bangkok.
• Environment: Thrives in humid tropical rainforests; favors well-drained soils rich in organic matter, along with a consistently warm climate and high ambient humidity that support its growth and seasonal flowering.

Leaves

• Large, somewhat lobed leaves
• Dark green with a glossy texture

Inflorescence (Spadix & Spathe)

• Includes a central spadix surrounded by a prominent spathe
• Attracts specific pollinators through visual cues and heat generation

Growth Habit

• Tuberous, terrestrial plant with a pronounced rhizome that stores nutrients
• Includes a dormant period, during which the tuber remains underground

Light Requirements

• Bright, indirect light
• Partial shade that mimics its native forest understory is idea

Watering & Humidity

• Requires regular watering to maintain moist but not waterlogged soil
• High ambient humidity is beneficial, and misting may help in drier environments

Soil & Potting Mix

• A well-draining mix enriched with organic matter
• Combination of loam, peat, and perlite works well

Temperature & Fertilizer

• Warm environment with temperatures between 70°F and 85°F (21°C to 29°C)
• A balanced, diluted fertilizer every two to four weeks 

Division and Cuttings

• Most common propagation method is through division of the tuber or rhizome
• Should be done during the dormant season to minimize stress on the plant

Seeds

• Germination process may be slow and erratic
• Requires a warm and humid environment with careful attention to soil moisture and temperature

Typical Issues

• Spider mites, mealybugs, or aphids
• Root rot can occur if the soil remains overly wet, especially during cooler periods

Treatment Recommendations

• Organic insecticidal soaps or neem oil 
• Adjusting watering practices and applying fungicides

• Folklore surrounding dramatic blooming events has elevated the plant to a symbol of natural wonder
• Unique flowering cycle and imposing inflorescence have also become a subject of study among botanists

• Prized for its rare display of inflorescence and the botanical curiosity it presents
• Striking appearance makes it a centerpiece in specialized tropical plant collections

Wild Population Status

• Habitat loss and collection pressures remain concerns in some areas

Market Availability

• Not broadly available in the mainstream horticultural market
• Tends to be found in the collections of dedicated growers and botanical gardens, and may command a premium price due to its rarity
