Nursery contributed plant descriptions

One of the most desirable of all cobra lilies with its incredible burgundy spathe, Arisaema sikokianum has a pure white interior and pure white knobbed spadix. Plant in well-drained soil that is dryish in the winter such as on a slope or near or under evergreen shrubs or trees. 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.

Silver foliage form. THE BEST. Simply amazing, this jack in the pulpit has deep purple on the outside of the flower and snow white inside. We don't always have A. sikokianum available, so when you get a chance, better jump.

This woodland perennial “Jack-in-the-Pulpit” has to be seen to be believed. The deep purple glossy “hood” of the spathe surrounds the pure glistening white of the club-like spadix – a striking color combination. The plant rises to around one or two feet in height in early spring from an underground, tuber-like structure. In addition to the “out of this world” flowers, the foliage is often marked with silver streaking. Best in woodland conditions and soil (similar culture to trilliums, hostas, etc.).

This is one of the most stunning species. Soon after the plant emerges in spring, a huge maroon pitcher shaped flower unfolds and reveals a bright white, club-like spadix. To add drama, the hood is striped. To top it off, this is one of the easiest to grow.

Very pretty and fairly hardy (Jelitto), this Asian Jack-in-the-Pulpit offers elegant 5-parted leaves (green sometimes marked with silver) and tall "pulpit" flowers of deep-purple veined with white in spring.PSh-SH/M

This the Liberace of the Arisaema not to be out staged by any of the competition. Unreal marshmallow looking spadix and leaves marked with a wash of white.
