Skunk cabbage

Description:

Lysichiton americanus, also called western skunk cabbage (USA), yellow skunk cabbage (UK),[1] American skunk-cabbage (Britain and Ireland)[2] or swamp lantern, 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.The plant grows from rhizomes that measure 30 cm or longer, and 2.5 to 5 cm in diameter. The short-stalked leaves are the largest of any native plant in the region, 30–150 cm long and 10–70 cm wide when mature. Its flowers are produced in a spadix contained within a 7–12 cm, large, bright yellow or yellowish green spathe atop a 30–50 cm stalk. The flowers are numerous and densely packed. It is among the first flowers to bloom in late winter or early spring.[3][4][5] Unlike the genus Symplocarpus (which includes S. foetidus, the eastern skunk cabbage), the flowers of Lysichiton species do not produce heat,[6] although this is widely and incorrectly said to be the case.[7-Wikipedia

Habitat:

L. 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.[8][9] 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.[10]-Wikipedia
