Amorphophallus krausei Engl.

• Genus: Amorphophallus
• Botanical Background: Described by botanist Adolf Engler. Its discovery added to the growing list of giant-flowered species within the Amorphophallus genus, which includes the famous Amorphophallus titanum.

• Geographical Range: Found primarily in tropical Southeast Asia, particularly in Malaysia and surrounding areas; it thrives in the dense, humid rainforests of this region
• Environment: Naturally grows in humid, warm climates with well-drained, nutrient-rich soils; it prefers low to mid-altitude regions, where it can receive ample rainfall and indirect sunlight.

Leaves

• Large and have a palmate shape, with a glossy texture
• The leaf color is generally deep green, with a slight sheen that makes it stand out in the forest undergrowth

Inflorescence (Spadix & Spathe)

• Large and has a distinct appearance, with a spadix that can be up to 1 meter tall
• The spathe is typically pale with greenish tones
• Produces a faint odor during its flowering period

Growth Habit

• Terrestrial and grows from a large tuber
• Not an epiphyte and does not climb
• The plant’s life cycle includes a dormant period, during which it stores nutrients in its tuber
  

Light Requirements

• Prefers bright, indirect light
• Should be protected from direct sunlight, which can scorch its leaves

Watering & Humidity

• Thrives in high humidity
• Should be watered regularly to keep the soil moist, though it should never be waterlogged
• During the dormant period, reduce watering

Soil & Potting Mix

• A well-draining, rich potting mix that includes organic material is ideal
• A mix of peat, perlite, and orchid bark is commonly recommended

Temperature & Fertilizer

• Between 18°C and 27°C (64°F to 81°F)
• Balanced liquid fertilizer, about once a month

Division and Stem Cuttings

• Division of the tuber during the dormant season
• Ensure each division has at least one viable bud

Seeds

• Possible but is more challenging
• Should be sown immediately after ripening in a moist, warm environment

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
  

• Often noted for its striking, large spadix, making it a subject of interest in botanical gardens and research on plant pollination mechanisms
• Has a brief flowering period
• Prized for its impressive flower and unique growth habit
• Its rarity and dramatic appearance make it a sought-after specimen for collectors
  

Wild Population Status

• There are no significant conservation concerns currently associated with Amorphophallus krausei, though habitat loss in Southeast Asia poses a general threat to tropical plant species

Market Availability

• Not as commonly available as other Amorphophallus species
• Can occasionally be found in specialized plant nurseries or through collectors
