Nursery contributed plant descriptions

Arisaema consanguineum forms fantastic four to five foot umbrellas of multiple leaflets that rise dramatically from amongst hostas and ferns in my part shade garden. This is an easy and intriguing addition to the part shade to part sun border that will add drama and structure in spades. 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.

The odd jack-in-the-pulpit you see in old gardens in Portland. Tough, dependable. Cobra-shaped flowers with an ‘odd’ smell. Leaves bold to 3 ft. Half sun, summer dormant. China. Frost hardy in USDA zone 6.

Wonderful in the shade: 3-6'tall "snake-skin" stems with large leaves divided into 12 slenderly tipped leaflets. This is one of the hardiest, easiest Arums to grow. Have been used in Chinese medicine for thousands of yrs. Sh/M/not dry

(JACK IN THE PULPIT) A good beginner’s Ariseama, ‘Jack’ is a perennial that sends up 30” stems in late spring/early summer and each is topped by a round umbrella leaf composed of twelve smaller leaflets with drooping thin tips…hooded spathe flowers of purple and white follow, the ‘hoody’ ends in another long drooping thin tip over the opening. Bizarro! At home in the woodland, especially nice in a group. Rich, moist, well drained soil, light shade. Red orange seed pods follow flowers. USDA Z5-8

One of the most garden-tolerant and easiest to grow of the cobra lilies: an umbrella of wavy leaflets, and a purple-striped, hooded flower in June. Water dormant bulbs only when dry.

Jewel of the woodland garden, this elegant, easy-to-grow species is found throughout southwestern China. A whorl of numerous narrow leaflets with slender drip-tips and undulating edges crowns each tall stately stem. Conjuring mysterious images of a cobra poised to strike, the otherworldly inflorescence is borne from a petiole beneath the foliage. It is defined by a purplish brown and greenish white-streaked spathe with an elongated hood that tapers to a pendulous, very long, threadlike tip. Clustered, bright scarlet berries create a colorful grand finale. Fertile, humus-rich and evenly moist soil will keep the Cobra Lily charmed. This plant will be shipped from fall through mid-spring. Most of the plants will be shipped dormant and bare-root unless we have potted ones which have sprouted. Dormant Arisaemas in containers must not be kept wet. Water them in their pots only when the soil gets bone dry

The easiest member of a group that is becoming quite popular because of their unusual looks and cultural ease; leaves are arranged like an umbrella frame with undulating edges and long drip tips while the "flowers" look like a cobra rising to strike.

By: Keeping it Green Nursery

From the Himalayan Mountains. Requires mulch for protection in colder areas. Consanguineum is one of the larger Variety's and can get over 4 feet tall, it is also one of the most cold hardy of the Arisaemas. The whip like extension on the hood is one of its unique features. These bulbs are the size approx of a golf ball Healthy Bulbs. Best handled and transported during the cold season.

Giant Himalayan Cobra Lily is a welcome addition to the shade garden. It sends forth tall (3-6') stalks topped with umbrellas of dissected foliage. The unusual purple and green striped spathe appears in early-mid summer, and is followed by tight clusters of orange red fruit. Good drainage is essential for overwintering, although it appreciates fertile moist soil while in active growth. Potted 2-2.5" bulbs.
