Arisaema sikokianum is considered the most stunningly beautiful member of the aroid family and, in particular, the genus Arisaema...heck, make that the entire plant kingdom! From an underground tuber in early spring (early April in NC), the dark pitcher and two five-lobed leaves emerge on a 1' tall fleshy petiole (stalk). As the pitcher opens, it reveals a swollen, pure white, protruding sex organ (spadix) which provides a dramatic contrast to the purple of the pitcher (spathe). Since Arisaema sikokianum doesn't offset or engage in sexual self-satisfaction, you'll need more than one to start a family. After flowering, the foliage remains attractive until it goes dormant in late summer. Arisaema sikokianum prefers a well-drained dry site in the woodland garden.
