Arisaema pattaniense Gagnep.

• Genus: Arisaema
• Botanical Background: Described by the botanist François Gagnepain, the species has garnered attention in botanical studies for its unique morphological traits. Historical records highlight its contribution to understanding aroid diversity in Southeast Asia

• Geographical Range: Native to the tropical and subtropical forests of Southeast Asia, particularly in regions of Indochina.
• Environment: Flourishes in well-draining, organically rich soils with high humidity; typically experiences mild to warm temperatures.

Leaves

• Broad with a slightly lobed or divided structure
• Rich green hue 
• Subtle variegation
• Texture is generally smooth

Inflorescence (Spadix & Spathe)

• Hood-like spathe that may display varying shades of green and hints of coloration along the margins
• Central spadix, less conspicuous, plays a key role in attracting pollinators

Growth Habit

• Terrestrial perennial
• Develops from a rhizomatous structure
• Form clumps over time

Light Requirements

• Bright, indirect light or partial shade
• Filtered sunlight under a forest canopy mimics ideal conditions

Watering & Humidity

• Regular watering is essential
• High humidity; regular misting or placement in a humid environment
• Consistent moisture

Soil & Potting Mix

• A rich, well-draining potting mix with ample organic matter is ideal
• Incorporating components like peat and perlite

Temperature & Fertilizer

• Moderate temperature range typical of tropical climates
• Balanced, diluted fertilizer applied during the growing season

Division and Cuttings

• Most commonly achieved through the division of the rhizome
• Dividing established clumps during the dormant period

Seeds

• Less common due to slow germination rates
• Used, a period of stratification may enhance germination success

Typical Issues

• Spider mites, aphids and mealybugs
• Root rot

Treatment Recommendations

• Insecticidal soap and organic fungicides
• Ensuring proper drainage and avoiding excessive moisture

• Mystical qualities, and its unusual inflorescence has inspired comparisons to abstract art
• Unique structure also makes it a subject of interest in botanical research
• Prize this species for its rare and eye-catching appearance
• Distinctive spathe and textured leaves add an exotic element

Wild Population Status

• Localized populations may be vulnerable to habitat loss and overcollection

Market Availability

• Not widely available in mainstream nurseries and is typically found through specialized collectors and botanical exchanges
