Arisaema concinnum Schott

• Genus: Arisaema
• Botanical Background: Described by botanist Heinrich Wilhelm Schott, a prominent figure in the study of the Araceae family, during the 19th century.

• Geographical Range: Native to the tropical and subtropical regions of Southeast Asia, particularly found in countries like China, India, and Nepal.
• Environment: Thrives in shaded, moist environments such as temperate forests or mountain slopes; prefers well-drained, humus-rich soils and requires high humidity levels and consistent moisture to grow well.

Leaves

• Large, glossy, and divided into leaflets
• They exhibit a striking green coloration with occasional dark markings along the veins, providing an attractive contrast

Inflorescence (Spadix & Spathe)

• Consists of a unique spathe that is pale green to purplish with a slight sheen
• The spadix is dark purple, and the flowers are surrounded by the hood-like spathe
• Uses its distinctive coloration to attract pollinators like beetles and flies

Growth Habit

• A terrestrial plant that grows from a rhizome
• Does not climb or spread horizontally but remains as an upright, compact plant
• Its growth is slow and steady, typically reaching heights of 20-30 cm
  

Light Requirements

• Prefers moderate to low light, ideal for shaded areas or filtered sunlight
• Avoid direct sunlight, which can scorch the leaves

Watering & Humidity

• Water consistently to keep the soil moist, but not soggy
• Thrives in high humidity, ideally above 60%
• Perfect for terrariums or shaded garden beds with good air circulation

Soil & Potting Mix

• A well-draining, slightly acidic potting mix with organic matter is recommended
• A mix of peat, perlite, and pine bark is often used to replicate its natural habitat

Temperature & Fertilizer

• Maintain temperatures between 15°C to 25°C
• Balanced liquid fertilizer diluted to half strength monthly

Division and Cuttings

• Typically done through division of the rhizomes in spring before new growth begins
• Ensure each division has at least one healthy growing shoot

Seeds

• Require a long germination period
• Must be kept in consistently moist conditions with temperatures around 20°C to promote germination

Typical Issues

• Spider mites, aphids, and mealybugs
• Root rot can also occur if the soil is kept too wet

Treatment Recommendations

• Use insecticidal soap or neem oil to treat pest infestations
• Ensure well-draining soil and avoid waterlogging to prevent root rot

• Have been used for their purported medicinal properties, although they must be handled with care due to the plant's toxicity
• The elegant spathe and glossy leaves make it prized for ornamental use in shady gardens and botanical collections

Wild Population Status

• While not currently classified as endangered, habitat destruction poses a threat to its natural populations
• Conservation efforts focus on preserving its native forest habitats

Market Availability

• Somewhat rare in the horticultural trade
• Available through specialty plant nurseries and botanical gardens, often in limited quantities
