Amorphophallus serrulatus Hett. & A.Galloway

• Genus: Amorphophallus
• Botanical Background: Described by botanists Hett. and A. Galloway, the species has been of interest due to its unusual floral structure and its description has enriched the botanical understanding of aroid diversity and informed later taxonomic revisions within the genus.

• Geographical Range: Indigenous to tropical regions of Asia.
• Environment: Thrives in humid, shaded conditions typical of tropical rainforests and favors well-drained soils enriched with organic matter and benefits from climates that deliver consistent moisture and moderate temperatures.

Leaves

• Large and irregularly lobed
• Vibrant green coloration with a moderately textured surface
• Medium to deep green coloration

Inflorescence (Spadix & Spathe)

• Spadix is centrally positioned and contrasts with a broad, serrated spathe
• Scent is generally mild or neutral
• Adapted for specialized pollination strategies

Growth Habit

• Terrestrial plant emerging from a tuberous rhizome
• Displays a seasonal growth habit with a distinct period of dormancy

Light Requirements

• Bright, indirect light that mimics its natural forest understory habitat

Watering & Humidity

• Consistent watering is essential
• Top layer of soil dry between watering sessions
• High humidity further supports its growth

Soil & Potting Mix

• A rich, well-draining potting mix that incorporates organic matter
• Containers should ensure proper drainage

Temperature & Fertilizer

• Maintain temperatures between 70°F and 85°F
• Balanced fertilizer on a regular schedule

Division and Cuttings

• Propagation is via division of the tuberous rhizome
• Helps ensure the preservation of genetic traits and facilitates the production of additional plants

Seeds

• When propagation by seeds is attempted, consider pre-germination treatments

Typical Issues

• Spider mites and mealybugs
• Occasional incidences of root rot linked to overly moist conditions

Treatment Recommendations

• Neem oil or insecticidal soap
• Reducing watering frequency and applying a suitable fungicide

• Sparked interest in studies of floral evolution within aroids
• Dramatic appearance has led to its occasional mention in botanical literature

• Admired for its rare morphology and the striking visual impact of its blooming cycle
• Coveted addition to advanced and specialized botanical collections

Wild Population Status

• No immediate global threats
• Localized environmental pressures could impact wild populations

Market Availability

• Not common in the mainstream horticultural trade
• Typically sourced from specialist nurseries or botanical exchanges
