Arisaema (Jack-in-the-Pulpit, Cobra Lily)
The flowrers are made up of a hooded tube and an elongated or rounded spadix inside the spathe. They can be beautiful or bizarre, but they always invite comment. Tall species are great "pop-up"plants among shade plants such as hostas or ararums. Different species can offer a succession of bloom from early spring to early summer. All can have showy heads of red fruit in fall.

In the garden arisaemas require shade and well-drained soil that is not dry in spring and early summer. Plant corms about 5" deep in humusy or gravelly well-drained soil. A loose mulch can help with species of borderling hardiness.

All our arisaema corms are BLOOMING SIZE. They are shipped in fall packed in dry sphagnum moss as soon as they are completly dry. We can not ship before this process is complete because the corms will rot in transit. After receiving the corms, keep them cool and dry, around 40 degrees F. is ideal. After potting, water only lightly until the shoots appear. Overwatering is the greatest danger. After growth begins, keep them in cold frames or a cold greenhouse.
