Description
Arisaema nepenthoides, the pitcher cobra lily, brings an air of mystery to shaded borders and woodland corners. Emerging in spring before its foliage, each flower seems conjured from the forest floor—a pale green spathe streaked in black and white, delicately twisted and fluted like a rare piece of glass. The effect is otherworldly yet oddly elegant, its streaky stem and hooded form calling to mind both pitcher plant and cobra. Later, the handsome leaves of Arisaema nepenthoides appear, dark green and fingered into five or seven leaflets, held aloft on yellow-green stems handsomely splashed with black.
Standing around 90cm tall, Arisaema nepenthoides is a plant of quiet confidence and considerable poise. It enjoys humus-rich soil and dappled shade, thriving in the company of ferns, hostas and other lovers of cool, damp woodland settings. Though its appearance is exotic, it’s surprisingly hardy and reliable once settled. The pitcher cobra lily rewards the observant gardener with a performance of subtle drama and refined intrigue—an elegant reminder that beauty often hides in the shadows.
The common name pitcher cobra lily nods to its spathe's dual character—part elegant pitcher, part cobra poised in hypnotic stillness.
