Nursery contributed plant descriptions

Arisaema jacquemontii has green spathes with white stripes. The tip of the spathe is often one to four inches long and green or purple. The spadix has a purple tongue-like appendage. The leaf stems often have reddish colouration. From Pakistan to Bhutan and western China. Arisaema are known as cobra lilies or jack-in-the-pulpits. There are only two North American species but many in Asia. They grow in moist, shaded, forested habitats and are great for adding cool foliage and floral intrigue in the shade or woodland garden where they can rise up and through other shade plants. In colder climates they can be grown in pots and protected in winter. Keep just above freezing. In pots, plant in a moist but free-draining mix of coarse bark and pumice or perlite. Pull back on watering when dormant.

From the Himalayan Mountains. Requires mulch for protection in colder areas. The Spathe ( bloom) is a light green with delicate white lines.The spadix widens as it reaches upwards. A nice cold hardy and compact plant, they make a wondeful splash of green in rock gardens. Healthy Bulbs. Best handled and transported during the cold season.
