Arisaema parisifolium J.Murata

• Genus: Arisaema
• Botanical Background: Described by J. Murata, this species has attracted the attention of botanists interested in the diversity of Asian aroids. Its classification has been refined through both classical taxonomy and modern molecular methods

• Geographical Range: Native to select regions of Asia where it is found in forested and montane environments
• Environment: Thrives in humid conditions with well-drained, organic-rich soils; grows in shaded or semi-shaded forest understories

Leaves

• Broad
• Lobed leaves; mix of green hues 
• Subtle variegation
• Texture is smooth 
• Slightly leathery feel

Inflorescence (Spadix & Spathe)

• Elaborate spathe
• Shades of green, cream, or subtle hints of red
• Not strongly scented

Growth Habit

• Terrestrial
• Develops from a rhizome that helps it survive in its native forest floor environment

Light Requirements

• Bright but indirect light
• Thrives when protected from direct sunlight, which can scorch its delicate leaves

Watering & Humidity

• Regular watering is essential
• High humidity

Soil & Potting Mix

• A well-draining potting mix rich in organic matter is ideal
• A blend that includes components like peat and perlite

Temperature & Fertilizer

• Moderate temperatures, typically ranging from 65°F to 75°F
• Balanced, water-soluble fertilizer applied every four to six weeks during the growing season

Division and Cuttings

• Most commonly achieved through the division of the rhizome
• Ensures that each new plant maintains the genetic traits of the parent

Seeds

• Less reliable
• Require a period of stratification and must be sown on a sterile, well-draining medium to promote germination

Typical Issues

• Spider mites and mealybugs
• Root rot

Treatment Recommendations

• Neem oil and mild insecticidal soaps
• Ensuring proper drainage and reducing excess moisture
• Chemical treatments should be used sparingly
  

• Garnered interest due to its unusual inflorescence structure
• Unique appearance plays an important role in ecological interactions within its native habitat
• Prize for its ornamental value and rarity
• Striking spathe and dynamic foliage patterns make it a standout specimen in aroid collections and specialized botanical displays

Wild Population Status

• While specific conservation assessments may vary regionally, not known to be widespread

Market Availability

• Rare in cultivation
• Primarily available through specialist nurseries and botanical societies
