Arisaema (Jack-in-the Pulpits) are a delightful addition to any shade garden. We carry several Asian varieties from China and Japan, as well as, many from the Himalayas. The unusual flowers consist of a spathe (hooded tube) that surrounds a spadix (which can take many forms) and come in a variety of colors. The foliage is usually very tropical appearing and the plant grows from a corm or tuber. Grow Arisaemas in a moist but well-draining soil that is slightly acidic and rich in humus. They prefer a shaded site and protection from late spring frosts. Flowers usually appear in spring or early summer. Plant the corms about 4-5” deep. Removal of the spent flowers will increase the vigor. Protect from slugs and mulch in the winter. If grown in pots overwatering is the greatest danger. Most Arisaemas are hardy from zone 5-9.
Arisaemas can only be shipped in early spring and not after April 15th.
A. concinnum [Zone 6-9] One of the prettiest in the genus and has a single radiate leaf which carries 7-11 leaflets. The spathe is pure green or dark purple with 5 broad vertical white stripes. Found growing in humusy soil on temperate forest floors and will do well in woodland gardens. Flowers in May and June.
A. consanguineum [Zone 5-9] Quite tall and has a single leaf divided into 12 leaflets. Spathe is purple brown with white stripes held on a “snake-skin” patterned stem.
A. costatum [Zone 6-9] Native to central and eastern Nepal and has a leaf divided into 3 leaf-lets…gets its name from the exaggerated ribs on the undersides of the leaflets. The spathe is dark purple with white stripes. Flowers in early June.
A. galeatum [Zone 6-9] This one is called the “Helmeted” cobra-lily because of the way the spathe recurves and gives a helmet-like shape to the flower. The spathe is light green with vertical white lines and is held below the foliage that is a 3-segmented leaf. In nature A. galeatum grows in deep shade and blooms in late May.
A. griffithii [Zone 5-9] This one blooms in April or May with a large green and purple spathe that resembles a cobra’s hood and has large erect leaves. The spathe is wide and twisted.
A. griffithii var Pradhanii [Zone 5-9] Selected clone of A. griffithii and probably the best form of this “cobra lily” with a stunning, huge spathe that has a bizarre shape and is extremely wide. Great color contrast.
A. nepenthoides [Zone 6-9] From the Himalayas and grows to be quite tall. The striped and spotted spathe is wide and pitcher-like making it one of the loveliest. Leathery umbrella-like foliage is dark green with various markings of red and brown. The stem is prominently mottled and looks similar to snakeskin. Blooms in April and May.
A. ringens [Zone 5-9] Common Asian species with glossy gray-green trifoliate leaves under which a green and purple striped spathe that is “hooded” and blunt-tipped is tucked. One of the easiest and longest lasting to grow.
A. serratum [Zone 5-9] A vigorous Asian species from Japan that can reach 3’ tall…flowers are green and purplish-brown striped and are held above two leaves that are di-vided into many leaflets. The spathe is hooded.
A. sikokianum [Zone 5-9] Most dramatic and stunning Arisaema…once one has seen this flower its a “must have”. Not only beautiful but also fairly hardy and easy to grow. A thick pure white spadix shaped like a golf tee is displayed against an erect purple and white-striped spathe that flares and ends with a long-pointed tip. Two dark green leaves are divided into five parts. Blooms early to mid spring.
A. speciosum [Zone 6-8] Native to the Himalayas and best attempted in mild cli-mates as does not do well in too much heat. The dark reddish to purple striped spathe is very attractive and held under one leaf divided into 3 segments.
A. speciosum var Magnificum [Zone 6-9] Magnificum is a very large selection of A. speciosum and a magnificently stunning plant. Flowers and leaves are similar but just a lot larger.
A. tortuosum [Zone 6-9] From the Himalayas and can grow to be quite tall…two leaves are divided into many long narrow leaflets and are topped with a green spathe. Spadix is quite long and extends up like a buggy whip. Blooms in late spring.
A. utile [Zone 5-9] Single trifoliate leaf is green with maroon veining. The spathe is cobra-like with a maroon hood that has white stripes and is held below the leaf. Found growing in humusy soil on temperate forest floors.
