(Jack-in-the-pulpit)
Excellent for shade garden or large containers.  Two species in this genus are native to Canada, Arisaema triphyllum (Jack-in-the-pulpit) and A. dracontium (Green Dragon), but over a hundred exist worldwide.
 

Arisaema amurense

Description: H60cm.   A green and white spathe emerges early in the season with fresh green foliage. This is a plant from shady locations in eastern Asia. Blooms in spring. Hardy to Zone 5 (deep planting and winter protection is recommended).  Easy to grow and multiply from seed or side tubers. 

 

Arisaema candidissimum  

Description: Three-part leaves and white or pink hoods over the spadix. It produces a clump over time. Hardy to at least Zone 5 (deep planting recommended). Sometimes late to emerge in the spring.  It may also be grown in deep (14in.+) containers and the tubers stored in the fridge over winter in slightly damp peat moss.

   Arisaema consanguineum

Description: H150cm.  A tall umbrella of leaflets shades a green/purple cylindrical spathe that ends in a long tail. This is a plant from open forests and hillsides in Northern India, Thailand and into China. Blooms early summer. Hardy to Zone 5 (deep planting and winter protection is recommended) 

Where to Use:Part sun/Part Shade. Fertile, well-drained soil. This species is sometimes slow to emerge in the spring (May-June), so mark where the tuber is buried. It may also be grown in deep (14in.+) containers and the tubers stored in the fridge over winter in slightly damp peat moss.

   Arisaema flavum 
 Description: H30-40cm. This species is unusual for its inflorescence with a yellow hood, accompanied by bright green leaves. Flowering in early summer.  Hardy to Zone 4

Description: H60cm, W60cm; Bold, glossy leaves are followed in summer by a spectacular striped purple/white spathe (5-10cm) forming a hood over the spadix and ending in a tail. In the fall fertilized stalks form a cluster of red berries and the foliage turns bright yellow. Native to Western China. Hardy to at least Zone 5 (winter protection recommended).

Where to Use:Part sun in well-drained soil. Tubers will form large clumps over time. It may also be grown in deep (14in.+) containers and the tubers stored in the fridge over winter in slightly damp peat moss.
