Himalayan Jack-In-The-Pulpit. Arisaema tortuosum. The 4' tall, stalk emerges in early June, topped with two tropical-looking palmate green leaves near the top. The Jack-in-the-pulpit flower is green in color, with a whip-like tongue that extends from the mouth of the flower upwards to 12 or more inches. It is native to the Himalayas. Later in the summer, the flower is replaced by a black seed cluster that turns red by autumn. A very hardy wildflower, once planted it naturalizes well. It does best in shade or part-shade.
