Identification and Description
Your identification of the Himalayan Cobra Lily (Arisaema consanguineum) begins with its distinct foliage and flower structure.
This perennial plant is recognized for its large, umbrella-like leaf. Each leaf comprises 11-20 narrow, glossy leaflets radiating from a central point, resembling a more diminutive palm tree leaf.
This plant features a singular, sturdy stem that can grow up to 1 meter (3.3 feet) in height. The stem is a dark, sometimes mottled, tone which supports the foliage and the unique flower.
The flower of the Himalayan Cobra Lily is particularly striking:

- Spadix: The elongated central floral spike, which can be green or purple, carries the actual tiny flowers of the plant.
After flowering, the plant produces orange-red berries, which add to its ornamental value. These berries develop on a spike and signal the plant’s reproductive phase.
Your recognition of this species will be aided by its growth pattern:
- Height: Typically ranging between 3-6 feet (1-2 meters).
- Width: Approximately 12 inches (30 cm).
This plant unfurls its foliage in the spring to early summer, with its intriguing flowers appearing from late spring to midsummer. The brilliant foliage persists throughout the growing season, garnering keen garden interest.
Habitat and Distribution
The Himalayan Cobra Lily, Arisaema consanguineum, thrives in various soil types and conditions across its native and adapted regions, indicating its adaptability to different ecological niches.
Geographical Range
Your exploration of the Himalayan Cobra Lily’s geographical range reveals its origins in the mountainous regions of the Himalayas and Indochina. However, it is not just confined to these areas; it has spread to other parts of Asia, including China, the Philippines, North Thailand, and North Vietnam.
Ecological Requirements
The ecological needs of the Himalayan Cobra Lily are indicative of its resilience. When considering the suitable conditions for its growth, focus on:
