Lysichiton americanus, also called western skunk cabbage (US), yellow skunk cabbage (UK), [2] American skunk-cabbage (Britain and Ireland) [3] or swamp lantern, [4] is a plant found in swamps and wet woods, along streams and in other wet areas of the Pacific Northwest, where it is one of the few native species in the arum family.
The plant is called skunk cabbage because of the distinctive "skunky" odor that it emits when it blooms. This odor will permeate the area where the plant grows, and can be detected even in old, dried specimens. The distinctive odor attracts its pollinators, scavenging flies and beetles.
Although similarly named and with a similar smell, the plant is easy to distinguish from the eastern skunk cabbage ( Symplocarpus foetidus ), another species in the arum family found in eastern North America. A cross between it and a closely related species from Japan, also called "skunk cabbage" but less malodorous, is grown as an ornamental plant on the margins of British aquatic gardens.
The plant grows from rhizomes that measure 30 centimetres (12 inches) or longer, and 2.5 to 5 cm (1 to 2 in) in diameter. The short-stalked leaves are the largest of any native plant in the region, 30–150 cm (12–59 in) long and 10–70 cm (4–27+1⁄2 in) wide when mature. Its flowers are produced in a spadix contained within a 7–12 cm (3–4+1⁄2 in) large, bright yellow or yellowish green spathe atop a 30–50 cm (12–20 in) stalk. The flowers are numerous and densely packed. It is among the first flowers to bloom in late winter or early spring [4] [5] [6] (typically March–July). [7] Unlike the genus Symplocarpus (which includes S. foetidus , the eastern skunk cabbage), the flowers of Lysichiton species do not produce heat, [8] although this is widely and incorrectly said to be the case. [9]
Lysichiton americanus is found from Kodiak Island and Cook Inlet, Alaska south through British Columbia, Washington, Oregon, and Northern California as far south as Santa Cruz County. Isolated populations are also found in northeastern Washington, northern Idaho, Montana, and Wyoming. [10] [11]
The plant was introduced into cultivation in the United Kingdom in 1901 and has escaped to become naturalized in marshy areas in Britain and Ireland, for example in Hampshire and Surrey, including Wisley Gardens, and in the north and west of the UK. [12] Once established in an area, it can be very difficult to control. [13] In 2016, it was classified by the European Union as an invasive species. [14] This implies that this species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the whole of the European Union. [15]
It was used as an ornamental garden plant in Britain and Ireland, where it grows well in marshy conditions. As of 2018, the Royal Horticultural Society recommends that it should not be cultivated. [16]
Hybrids with Lysichiton camtschatcensis , called Lysichiton × hortensis, are also cultivated. These have larger spathes than either of the parent species. [12]
Flies are drawn by the odour to pollinate the flowers. [7]
While some consider the plant to be a weed, deer may browse the leaves, and its roots are food for American black bears. After emerging from hibernation, bears eat it as a laxative or cathartic. [17]
The plant was used by indigenous people as medicine for burns and injuries, and in times of famine as an emergency food source, when the leaves were heated and eaten. The leaves have a somewhat spicy or peppery taste. [17]
Although the plant was not part of human diet under normal conditions, its large, waxy leaves were important to food preparation and storage. They were commonly used to line berry baskets and to wrap around whole salmon and other foods when baked under a fire. [17] [7]
The leaves were also used as a medicated bandage to cure sores and swelling.[ citation needed ] Its sap was used as a treatment for ringworm. [7]
The plant contains calcium oxalate crystals, which result in a prickling sensation on the tongue and throat [17] and can cause intestinal irritation; if consumed in large quantities it can even cause death.
The Araceae are a family of monocotyledonous flowering plants in which flowers are borne on a type of inflorescence called a spadix. The spadix is usually accompanied by, and sometimes partially enclosed in, a spathe. Also known as the arum family, members are often colloquially known as aroids. This family of 140 genera and about 4,075 known species is most diverse in the New World tropics, although also distributed in the Old World tropics and northern temperate regions.
Acorus calamus is a species of flowering plant with psychoactive chemicals. It is a tall wetland monocot of the family Acoraceae, in the genus Acorus. Although used in traditional medicine over centuries to treat digestive disorders and pain, there is no clinical evidence for its safety or efficacy – and ingested calamus may be toxic – leading to its commercial ban in the United States.
In botany, a spadix is a type of inflorescence having small flowers borne on a fleshy stem. Spadices are typical of the family Araceae, the arums or aroids. The spadix is typically surrounded by a leaf-like curved bract known as a spathe. For example, the "flower" of the well known Anthurium spp. is a typical spadix with a large colorful spathe.
Symplocarpus foetidus, commonly known as skunk cabbage or eastern skunk cabbage, is a low-growing plant that grows in wetlands and moist hill slopes of eastern North America. Bruised leaves present an odor reminiscent of skunk.
Skunk cabbage is a common name for several plants and may refer to:
Arum maculatum is a woodland flowering plant species in the family Araceae. It is native across most of Europe, as well as Eastern Turkey and the Caucasus.
Symplocarpus is a genus of flowering plants in the family Araceae, native to United States, Canada and eastern Asia. The genus is characterized by having large leaves and deep root systems with contractile roots used for changing the plant's level with the ground. Symplocarpus species grow from a rhizome and their leaves release a foul odor when crushed.
Lysichiton is a genus in the family Araceae. These plants are known commonly as skunk cabbage or less often as swamp lantern. The spelling Lysichitum is also found. The genus has two species, one found in north-east Asia, the other in north-west America.
Calla is a genus of flowering plant in the family Araceae, containing the single species Calla palustris.
Carrion flowers, also known as corpse flowers or stinking flowers, are mimetic flowers that emit an odor that smells like rotting flesh. Apart from the scent, carrion flowers often display additional characteristics that contribute to the mimesis of a decaying corpse. These include their specific coloration, the presence of setae and orifice-like flower architecture. Carrion flowers attract mostly scavenging flies and beetles as pollinators. Some species may trap the insects temporarily to ensure the gathering and transfer of pollen.
Vaccinium corymbosum, the northern highbush blueberry, is a North American species of blueberry which has become a food crop of significant economic importance. It is native to eastern Canada and the eastern and southern United States, from Ontario east to Nova Scotia and south as far as Florida and eastern Texas. It is also naturalized in other places: Europe, Japan, New Zealand, the Pacific Northwest of North America, etc. Other common names include blue huckleberry, tall huckleberry, swamp huckleberry, high blueberry, and swamp blueberry.
Helleborus foetidus, known variously as stinking hellebore, dungwort, setterwort and bear's foot, is a species of flowering plant in the buttercup family Ranunculaceae, native to the mountainous regions of Central and Southern Europe and Asia Minor. It is found wild in many parts of England, especially on limestone soil.
Sambucus nigra is a species complex of flowering plants in the family Adoxaceae native to most of Europe. Common names include elder, elderberry, black elder, European elder, European elderberry, and European black elderberry. It grows in a variety of conditions including both wet and dry fertile soils, primarily in sunny locations. The plant is widely grown as an ornamental shrub or small tree. Both the flowers and the berries have a long tradition of culinary use, primarily for cordial and wine.
Arum italicum is a species of flowering herbaceous perennial plant in the family Araceae, also known as Italian arum and Italian lords-and-ladies. It is native to the British Isles and much of the Mediterranean region, the Caucasus, Canary Islands, Madeira and northern Africa. It is also naturalized in Belgium, the Netherlands, Austria, Argentina, North Island New Zealand and scattered locations in North America.
Thermogenic plants have the ability to raise their temperature above that of the surrounding air. Heat is generated in the mitochondria, as a secondary process of cellular respiration called thermogenesis. Alternative oxidase and uncoupling proteins similar to those found in mammals enable the process, which is still poorly understood.
Phlox subulata the creeping phlox, moss phlox, moss pink or mountain phlox, is a species of flowering plant in the family Polemoniaceae, native to eastern and central USA, and widely cultivated.
Trillium nivale, the snow trillium or dwarf white trillium, is a species of flowering plant in the family Melanthiaceae. It is native to parts of the east and midwest United States, primarily the Great Lakes States, the Ohio Valley, and the Upper Mississippi Valley, as far north as central Minnesota.
Amorphophallus titanum, the titan arum, is a flowering plant in the family Araceae. It has the largest unbranched inflorescence in the world. The inflorescence of the talipot palm, Corypha umbraculifera, is larger, but it is branched rather than unbranched. A. titanum is endemic to rainforests on the Indonesian island of Sumatra.
Orontioideae is a subfamily of flowering plants in the family Araceae. The subfamily consists of three genera namely, Lysichiton, Orontium, and Symplocarpus. Characteristics of Orontioideae include medium-sized pollen grains and subterranean stems. Species in the subfamily have a base chromosome number of X=13.
Lysichiton camtschatcensis, common name Asian skunk cabbage, white skunk cabbage, Far Eastern swamp lantern or Japanese swamp lantern, is a plant found in swamps and wet woods, along streams and in other wet areas of the Kamchatka Peninsula, the Kuril Islands, Sakhalin and northern Japan. The common name "skunk cabbage" is used for the genus Lysichiton, which includes L. americanus, the western skunk cabbage, noted for its unpleasant smell. The Asian skunk cabbage is more variable: plants have been reported in different cases to smell disgusting, not at all, and sweet. In Japanese it is known as mizubashō from a supposed similarity to the Japanese banana, a name with poetic rather than malodorous associations. It is not closely related to the true cabbage.
