Alocasia odora (G.Lodd.) Spach

• Genus: Alocasia
• Botanical Background: Initially described by George Loddiges, this species was later classified by Spach in the 19th century. Known for its ornamental use, Alocasia odora has been a subject of botanical studies due to its large size and striking flowers.

• Geographical Range: Native to Southeast Asia, particularly found in tropical regions of Malaysia, Indonesia, and the Philippines.
• Environment: Thrives in warm, humid environments, typically growing along forest floors in tropical regions; prefers moist, well-drained soils and moderate to high humidity, with a temperature range of 20°C to 30°C.

Leaves

• Large, arrow-shaped, and glossy
• Rich green color
• Can reach up to 45 cm long and 30 cm wide, with smooth surfaces and pronounced veins

Inflorescence (Spadix & Spathe)

• Pale green spathe with a white spadix
• Produces a strong fragrance at night, which is characteristic of its name "Night-Scented Lily"
• Fragrance attracts nocturnal pollinators

Growth Habit

• Terrestrial species that grows from a rhizome
• Not epiphytic and requires a solid base for growth
• Can reach a height of 1.5 meters in ideal conditions

Light Requirements

• Bright, indirect light
• Direct sunlight may scorch its large leaves, so filtered light or partial shade is optimal

Watering & Humidity

• Keep the soil consistently moist, but avoid waterlogging
• High humidity is essential for healthy growth
• Ideal for humidifiers or misting if grown indoors

Soil & Potting Mix

• Well-draining soil is necessary, ideally a mix designed for tropical plants
• A peat-based mix with added perlite or orchid bark works well
• Ensure the container has good drainage
  

Temperature & Fertilizer

• Prefers temperatures between 20°C to 30°C
• Balanced liquid fertilizer diluted to half strength monthly

Division and Cuttings

• Typically done through rhizome division
• Ensure that each division has at least one healthy shoot or root to establish a new plant

Seeds

• Not commonly used for propagation due to the difficulty in germinating them

Typical Issues

• Spider mites, aphids, and mealybugs
• Root rot can occur if overwatered or kept in poorly draining soil

Treatment Recommendations

• Insecticidal soaps or neem oil are effective treatments for pest infestations
• To prevent root rot, ensure proper drainage and avoid overwatering

• Strong fragrance emitted by the flowers of Alocasia odora at night is a notable characteristic, attracting nocturnal pollinators
• Used for medicinal purposes, although it should be handled with care due to its toxic properties
• Highly prized for its large, glossy foliage and the unique fragrance of its flowers
• Often used as an ornamental plant in tropical gardens and as an indoor specimen in suitable climates

Wild Population Status

• There are no immediate conservation concerns
• Remains widely distributed in its native range
• Habitat loss in tropical areas poses a general threat

Market Availability

• Commonly available in nurseries and garden centers, especially in tropical and subtropical regions
• Also cultivated as a popular ornamental plant
