Cypress Spurge, H. Faubert, R. A. Casagrande Jan 2002

Cypress Spurge, H. Faubert, R. A. Casagrande

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Cypress spurge (Euphorbia cyparissias L.) is a herbaceous European perennial introduced into North America as an ornamental plant in the 1860s (Croizat, 1945). It was widely planted in graveyards and often is called graveyard weed (Muenscher, 1936). The plant escaped cultivation and became established on open ground, particularly in pastures (Stuckey and Pearson, 1973).

Slenderflower Thistle (Winged Slender Or Seaside Thistle), A. Gassmann, L.-T. Kok

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Like many other Carduus species, slenderflower thistle, Carduus tenuiflorus Curtis, is associated with pastures, disturbed areas, and vacant lots. Invasion is favored by annual burning of pastures. The thistle protects forage from grazing and is a competitive weed in improved pastures.

Leafy Spurge, R. M. Nowiersky, R. W. Pemberton Jan 2002

Leafy Spurge, R. M. Nowiersky, R. W. Pemberton

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Leafy spurge, Euphorbia esula L., is an invasive, deep-rooted perennial herb that is native to Eurasia. The plant spreads through explosive seed release and vigorous lateral root growth, forming large, coalescing patches that can dominate rangeland, pastures, prairies and other non-crop areas in the Great Plains region of North America.

Spotted Knapweed, J. Story Jan 2002

Spotted Knapweed, J. Story

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Spotted knapweed, Centaurea maculosa Lamarck, is a purple-flowered, herbaceous, perennial weed, living three to five years on average. It infests semiarid range lands in the western United States and roadsides and fields in the eastern part of the country. Infested areas are dominated by the plant, reducing their grazing value and suppressing native plant communities. The plant, originally from Central Asia, has been in North America for over 120 years.

Swallow-Worts, L. Tewksbury, R. Casagrande, A. Gassmann Jan 2002

Swallow-Worts, L. Tewksbury, R. Casagrande, A. Gassmann

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

There are three European species of swallow-worts found in North America: Vincetoxicum nigrum (L.) Moench (black swallow-wort), Vincetoxicum rossicum (Kleo.) Barb. (pale swallow-wort or dog strangling-vine), and Vincetoxicum hirundinaria Medik. (white swallow-wort) (Sheeley and Raynal, 1996). Swallow-worts are in the family Asclepiadaceae. Vincetoxicum nigrum and V. rossicum now are naturalized in northeastern North America, and both are invasive in natural areas and abandoned pastures (Lawlor, 2000). Swallow-worts are found in gardens and fields, along fencerows, roadways, grassy slopes, wooded edges, and streambanks. Tangled masses of swallow-wort vines shade and suppress native plants (Sheeley and Raynal, 1996). In Rhode Island, heavy …
