• Geographical Range: Native to regions of China and other parts of East Asia, where it grows in temperate to subtropical environments
• Environment: Thrives in forest understories and mountainous areas with well-draining, organic-rich soils and moderate humidity. The plant prefers environments with distinct seasonal changes

Leaves

• Lobed and divided
• Medium in size
• Glossy green surface
• Texture and pattern vary slightly

Inflorescence (Spadix & Spathe)

• Modest inflorescence consisting of a greenish spathe that encloses the spadix

• Dividing clumps with several buds can stimulate healthy regrowth
  

Seeds

• Less common owing to lower germination rates

Typical Issues

• Aphids and spider mites
• Overwatering may lead to fungal issues such as root rot

Treatment Recommendations

• Use insecticidal soap for pest management
• Ensure proper air circulation.
