Arisaema griffithii Schott

Introduction & Overview

Common and Scientific Names

  • Scientific Name: Arisaema griffithii
  • Common Name: Griffith's Jack-in-the-pulpit

Quick Facts

  • Origin: Native to the high-altitude regions of the Himalayas and neighboring mountains
  • Features: Easily recognized by its large, hooded spathe and striking dark purple coloration, often contrasting with the lush greenery of its native habitat

Taxonomy & Classification

  • Genus: Arisaema
  • Botanical Background: Described by Heinrich Wilhelm Schott, an Austrian botanist renowned for his work on the Araceae family. Schott's contributions were foundational in understanding the diversity of this plant family.

Natural Habitat & Distribution

  • Geographical Range: Found primarily in the mountainous regions of India, Bhutan, and Nepal, typically at elevations ranging from 1,200 to 3,000 meters.
  • Environment: Thrives in shaded, moist environments, often along streams and forested slopes. It prefers cool, humid conditions and well-draining, slightly acidic soil.

Morphological Characteristics

Leaves

  • Large, divided into several leaflets
  • Glossy, dark green appearance with subtle veins
  • They are often larger compared to other species in the genus

Inflorescence (Spadix & Spathe)

  • Spathe is large and hood-like, with a dark purple or maroon coloration, contrasting with the green foliage
  • Spadix is typically yellow and stands out beneath the spathe
  • Emits a faint, unpleasant odor to attract its pollinators, including flies

Growth Habit

  • Terrestrial, growing from a rhizome, and can reach up to 1 meter in height
  • Tends to grow in clusters, with each plant emerging from its own tuber

Cultivation & Care

Light Requirements

  • Prefers bright, indirect light
  • Does not tolerate direct sunlight, which can scorch its leaves

Watering & Humidity

  • Ensure the soil remains consistently moist, but not waterlogged
  • High humidity is preferred
  • Ideal for terrariums or humid garden environments

Soil & Potting Mix

  • A well-draining potting mix with organic matter, such as a blend of peat, perlite, and pine bark
  • A slightly acidic to neutral pH (6-7) is ideal

Temperature & Fertilizer

  • Thrives in temperatures between 18°C and 25°C (64°F to 77°F)
  • Balanced, slow-release fertilizer can be applied during the growing season

Propagation Methods

Division and Cuttings

  • Typically done through division of the rhizomes during the dormant season
  • Each division should have at least one growing bud to ensure success


Seeds

  • Need to be fresh and require a period of cold stratification before they will germinate

Common Pests & Diseases

Typical Issues

  • Aphids and spider mites
  • 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

Notable Traits & Uses

  • Believed to possess medicinal properties, though it is not widely used in traditional medicine
  • Also a popular ornamental species due to its striking appearance
  • Prized for its unique and dramatic floral structure, making it a favorite among Aroid collectors and enthusiasts
  • Especially valued in shaded garden beds or indoor collections where its exotic look can be admired

Conservation & Availability

Wild Population Status

  • Not listed as endangered, though it is sensitive to habitat destruction, particularly from logging and agricultural development in its native regions

Market Availability

  • Available in specialized nurseries and online
  • Availability can be somewhat limited due to its specific environmental needs
