Common name
This is the non-scientific name used for a plant. A plant may have several common names, depending on the gardener's location.

(Himalayan Cobra Lily) As its name implies, Poseidon is a tall, commanding Arisaema. We offer you a well-established clump that will reward you by blooming the first year that you plant it.

Poseidon's spathe is deep green and purple. It is a leaf-like blossom that wraps around and hangs over the finger-like spadix with its tip coming to a long, thin point. It looks a bit like a cobra hissing. Its blue-green, radial leaves spread out like spokes at the top of the plant's stalk -- called a psuedostem -- and have silver stripes down the center of each blade. Give this majestic plant full sun to partial shade and rich, well-drained soil.

Most Arisaemas are from Asia where they are known as Cobra Lilies. Arisaema consanguineum is native to lowlands as well as alpine areas in China, India, Taiwan, Thailand and Tibet. North American species are commonly called Jack in the Pulpit.

Plantswoman Ellen Hornig, who is particularly renowned for the Arisaemas she grew at the former Seneca Hill Perennials nursery in Ithaca, New York, bred this excellent cultivar. It grows well in full sun and survives chilly winters.

Arisaemas are used medically in herbal formulas, but should be carefully processed for safe consumption.
