Arisema, arisaema - sow, plant, nurture

Arisema, arisaema, flower with "cobra's head" or baroque poisonous spathe!

The arisemas are original to say the least. They form large erect calyxes, from which, depending on the variety planted, a fleshy piece appears like a small white or tinted phantom, sometimes it is a more or less visible central spike ... The flowers take on various colors but the more often dull. By discovering it in faraway lands one would readily ask the question of its venomosity ... But in reality, it is not. Nothing to fear !
If the flowers of the arisema are amazing, the palmate foliage is also to its advantage.
Moderately hardy, the arisaema needs protection in winter. It appreciates semi-shaded exposures such as cool soils.

How to divide it?

• When the plant is sufficiently established in the garden (2 years)
• Using a spade fork, dig up the root ball.
• Around the main corm (bulb), the plant has developed a network of small corms.
• They are the ones who can be separated but ...
• Only select those that measure more than 2 cm across.

Jack in the Pulpit Planting Zones, Sun & Soil Requirements, and Care

A jack in the pulpit is a species indigenous to the eastern parts of North America and it can be successfully grown in USDA hardiness zone 4-9.

It is crucial to growing this species in either partial shade or in full shade with adequate amounts of fertilization and watering. This species containing wildflowers do not need well-drained soils (depends on the different types of jack-in-the-pulpit), which is why they can do well in boggy soils. What you can do is mimic the native habitat of the species, which would be creating an acidic, damp area.

If you want to plant your own jack in the pulpit, what you have to do is dig a 6-inch hole on the ground and put the corm in it. As the springtime approaches, the plants peek through the soil and that is when you will need to shovel at least 2 inches of the mulch around it to conserve the moisture. Slugs and other pests like feeding on this wild plant, which is why you will need to be extra caring with this plant.

Arisaema triphyllum (Jack-in-the-Pulpit, Bog onion, Brown dragon, Indian turnip, Wake robin or Wild turnip) is a herbaceous perennial growing from a corm. It is a highly variable species, ranging from green on the spathe to deep purple. Grow it in the humus of rich woods, shaded form the hot sun. The species does poorly in heavy clay soils. Grown from seed, it takes four to five years to flower.

Arisaema triphyllum, commonly called Jack-in-the-pulpit, is a spring woodland wildflower usually growing 1- 2 'tall. The flower structure consists of the spadix (Jack) which is an erect spike containing numerous, tiny, green to purple flowers and the sheath-like spathe (pulpit) which encases the lower part of the spadix and then opens to form a hood extending over the top of the spadix. The outside of the spathe is usually green or purple and the inside is usually striped purple and greenish white, though considerable color variations exist. Two large green, compound, long-petioled leaves (1-1.5 'long), divided into three leaflets each, emanate upward from a single stalk and provide umbrella-like shade to the flower. The fleshy stalk and leaves lend an almost tropical aura to the plant. Flowering plants initially produce only male flowers, but become hermaphroditic as they further age (male flowers on upper part of spadix and female on lower part). Most plants in a colony will vanish by mid-summer (become dormant), but the mature, hermaphroditic flowering plant will produce a cluster of red berries in mid to late summer which becomes visible as the spathe withers. Roots contain calcium oxalate (same chemical as in Diffenbachia or dumb cane) and are poisonous (and a serious throat irritant).

The genus name comes from Greek words aris meaning arum and loved meaning red in reference to the red-blotched leaves found on some individuals.


Description

1 x seed packet containing 10x Arisaema kiushianum seeds.

From Japan, Arisaema kiushianum is a real gem! One of my favorite Arisaema species.

The spathes are held low down below the foliage and close to the ground. Despite this, they are beautifully colored and eye-catching. One of the most remarkable in the Arisaema genus.

Easy to grow, this rewarding plant will increase steadily after a few years. Grow in an airy ’compost. It does well in a pot, although ensure that the tubers are protected from frost. In the ground, they are hardy provided that the drainage is good.
