  • Common Name: Referred to by regional names in areas where it is native

Quick Facts

  • Origin: Native to select regions of Asia
  • Features: Tall, spadix-and-spathe inflorescence and unique leaf structure; it thrives in environments with high humidity and well-drained soils, making it a subject of fascination among aroid collectors

Taxonomy & Classification

  • Genus: Amorphophallus
  • Botanical Background: Historically, various botanists have examined its morphology and reproductive strategy, contributing to a richer understanding of its classification and evolutionary history.

Natural Habitat & Distribution

  • Geographical Range: Native to temperate regions of Asia and can often be found in forest edges and disturbed habitats. Its range is limited to areas where seasonal humidity and mild climates prevail.
  • Environment:  Well-drained, organic-rich soils with moderate to high moisture levels; it typically inhabits regions with warm summers and cooler winters, reflecting its adaptation to seasonal climates rather than perpetual tropical heat.

Morphological Characteristics

Leaves

  • Large and palmate with deeply divided segments
  • Deep green shades with a leathery texture
  • Subtle variegation along the margins

Inflorescence (Spadix & Spathe)

  • Cone-shaped spadix surrounded by a broad, sometimes mottled spathe
  • Spathe tends to be a deep reddish-purple or brown in hue
  • Emits a faint, musky odor during bloom
  • Scent is generally milder compared to related species

Growth Habit

  • Terrestrial and develops from an underground tuber
  • Produces a single, towering inflorescence from the tuber followed by a cycle of large, compound leaves

Cultivation & Care

Light Requirements

  • Bright, indirect light

Watering & Humidity

  • Regular watering schedule is ideal
  • Moderate to high ambient humidity

Soil & Potting Mix

  • A loose, well-draining mix rich in organic matter
  • A peat-based potting mix combined with perlite or coarse sand can ensure proper drainage and root health

Temperature & Fertilizer

  • Temperature range, ideally between 65 and 80°F (18 to 27°C)
  • A balanced fertilizer applied every 4 to 6 weeks during the growing season

Propagation Methods

Division and Stem Cuttings

  • Tuber division once the plant has completed its growth cycle
  • Each division should include a portion of the tuber with viable buds

Seeds

  • Less common due to variable germination rates
  • When attempted, seeds require a warm, humid environment 

Common Pests & Diseases

Typical Issues

  • Spider mites and aphids
  • Root rot 

Treatment Recommendations

  • Organic insecticidal soaps
  • Chemical treatments
  • Maintain well-drained soil
  • Avoid overwatering

Notable Traits & Uses

  • Local folklore sometimes ties it to seasonal renewal rituals
  • Unique structure and periodic flowering 
  • Dramatic inflorescence and substantial foliage display
  • Unusual appearance

Conservation & Availability

Wild Population Status

  • Not currently listed as endangered
  • Habitat loss and over-collection in some areas

Market Availability

  • Relatively uncommon in the retail market
  • Available through specialized nurseries and botanical exchanges
