Impacts: Jimsonweed is a very toxic plant. Most animals will stay away from it because of its foul odor. However, goats have been known to eat the plant, resulting in slow deaths from poisonings. This plant is on the Pennsylvania Noxious Weed List, meaning it is illegal to cultivate in the state of Pennsylvania. All parts of this plant are considered toxic. BioBullies Jimsonweed Datura stramonium *It is illegal to propagate, sell or transport this plant within the Commonwealth. Suspected Means of Introduction: Jimsonweed was introduced from Europe and was detected in Jamestown, Virginia, giving it the nickname “Jamestown weed”. Description: Jimsonweed is an annual plant that grows erect, and reaching heights of 5 feet. The flowers are trumpet or funnel shaped ranging from white to purple. They are also said to open and close in the evening hours, giving it the nickname “moonflower”. The fruits are approximately the size of a walnut, egg-shaped, and covered in prickles. When cut open, they split into four chambers, each with kidney shaped seeds. The leaves of the plant are large and irregularly toothed, with larger-looking lobed leaves, that resemble oak leaves. The plant gives off a strong, distinctive odor that may ward off animals. BioBullies Native Range: Jimsonweed is argued to have originated from India or Central America, some saying China then introduced in to Europe before making its way to the U.S. Jimsonweed Datura stramonium Resources for Identification and Control of Jimsonweed Weed of the Week - USDA Forest Service Plant Profile Database USDA Invasive.org University of GA, US Forest Service, USDA APHIS PA Invasive Exotic Plant Fact Sheet - DCNR Noxious Weed Fact Sheet PA Dept. of Agriculture Habitat: Jimsonweed can grow in most habitats but prefers nutrient-rich soils along road ways, sand dunes and places other weeds grow. It can be found in most of the U.S. and is tolerant of temperatures of both the southern and northern habitats. However , it thrives in the southern U.S., where it was originally found. Biology: Jimsonweed cultivates by the seeds growing from the Natural Biodiversity www.naturalbiodiversity.org pods at the top of the plant. With adequate moisture, seedlings produce from mid-May to mid -June. Control Methods: Jimsonweed can be controlled by destroying the seed source. Treating it like other weeds, jimsonweed can be mowed or cut to remove existing populations. Some herbicides can be used if the growth of the population is harder to control. 538 Park Avenue Johnstown, PA 15902 e-mail: [email protected]
