• Genus: Symplocarpus
• Botanical Background: First described by Makino, a prominent Japanese botanist, this species has long intrigued botanists for its adaptation to temperate, moist environments and its unusual flowering behavior

• Geographical Range: Indigenous to Japan and is pparticularly found in forested and wetland areas that provide a sheltered, moist environment
• Environment: Thrives in moist, organic-rich soils under partial shade, favors environments with high humidity and seasonal rainfall, typical of temperate forest ecosystems

Leaves

• Large, lobed leaves that form a basal rosette
• Deep green leaves
• Rough texture
• Exhibit a robust, healthy appearance

Inflorescence (Spadix & Spathe)

• Consists of a central spadix surrounded by a greenish spathe

Growth Habit

• Perennial terrestrial plant that grows from a sturdy rhizome, enabling it to survive in moist woodland settings

Light Requirements

• Best suited for bright, indirect light or partial shade, replicating its natural forest understory

Watering & Humidity

• Maintain consistently moist soil conditions
• High humidity to mirror its native damp environment

Soil & Potting Mix

• Plant in rich, well-draining soil with ample organic matter
• Potting mix that retains moisture while preventing waterlogging is ideal

Temperature & Fertilizer

• Thrives in cooler, temperate conditions
• Balanced fertilizer during the growing season supports healthy growth

Division

• Most common propagation method is rhizome division
• Usually performed in early spring when the plant is emerging

Seeds

• They have moderate viability
• Often benefit from a period of cold stratification to improve germination rates

Typical Issues

• Occasionally encounter pests such as aphids
• Fungal infections, particularly in high humidity conditions

Treatment Recommendations

• Apply organic insecticidal soap for pest control
• Ensure proper air circulation to prevent fungal issues
• Maintaining balanced moisture levels is key

• Culturally significant in Japan due to its early spring bloom and unique odor, which signal seasonal change
• Unusual inflorescence has made it a subject of interest in botanical studies

• Collectors prize its rarity and striking appearance
• Unusual structure and seasonal display make it a standout specimen in specialized collections

Wild Population Status

• Not currently classified as endangered

Market Availability
