Pinellia ternata (Thunb.) Makino

• Genus: Pinellia
• Botanical Background: Studied extensively by botanists in East Asia, with its classification refined over the years as botanical research advanced; early descriptions by notable botanists laid the foundation for its current taxonomic status.

• Geographical Range: Indigenous to East Asia, including regions in China, Japan, and Korea.
• Environment: Moist, shaded environments such as forest understories, preferring well-drained, humus-rich soils and moderate climates.

Leaves

• Simple, arrow-shaped leaves
• Medium-sized
• Slightly leathery texture
• Attractive green coloration

Inflorescence (Spadix & Spathe)

• Small, inconspicuous spadix enclosed by a protective spathe that is generally greenish or brownish
• Scent is mild
• Structure facilitates insect pollination

Growth Habit

• Herbaceous perennial
• Grows from tubers
• Maintains a clumping habit
• Low-growing groundcover rather than a climbing or epiphytic species

Light Requirements

• Bright, indirect light to protect its delicate leaves from harsh direct sunlight

Watering & Humidity

• Regular watering is essential
• Keeping the soil consistently moist while ensuring good drainage
• Moderate humidity levels are optimal

Soil & Potting Mix

• A rich, well-draining potting mix that incorporates organic matter 
• Containers with drainage holes work best

Temperature & Fertilizer

• Thrives in moderate temperatures 
• Avoiding extreme heat or frost
• Balanced fertilizer applied during the growing season to support healthy growth

Division and Cuttings

• Most commonly achieved by dividing its tubers during the dormant season

Seeds

• Viable, germination can be challenging and is less common in cultivation compared to vegetative propagation

Typical Issues

• Infestations of spider mites and mealybugs
• Potential root rot if the soil remains overly moist

Treatment Recommendations

• Maintaining proper air circulation and using organic insecticidal soap
• Root rot can be managed by adjusting watering practices and ensuring soil drainage

• Valued for its therapeutic properties
• Requires proper processing due to inherent toxicity in its raw form
• Unusual leaf shape and its ability to thrive in shaded garden areas

Wild Population Status

• Not currently listed as endangered
• Sustainable harvesting and habitat preservation are important to maintain its natural populations

Market Availability

• Moderately available in specialized nurseries and through online plant retailers
