Senecio flaccidus
Also called Threadleaf Groundsel
Threadleaf ragwort (Senecio flaccidus) is a fast-growing, short-lived bushy perennial shrub of the daisy family from dry, gravelly areas of central and southwest North America. It grows well in full sun and sharp drainage, and it is better suited to rangelands and dry gardens than to lush beds.
Senecio flaccidus, also known as threadleaf ragwort, is a member of the daisy family. It is native from central to southwest North America, where it is common in gravelly and dry areas.
The species is poor forage for cattle and horses due to the alkaloids contained in the plant; these cause liver disease when consumed in large quantities.
Also known as Senecio longilobus, one of the alkaloids found in this species is longilobine, as well as senecionine, seneciphylline, florosenine, otonecine-based florosenine, and retrorsine.
S. flaccidus can be found from the central to the southwestern United States, overlapping with the Great Plains region. It is native between Utah and Kansas, south to Arizona, New Mexico and Texas, and much of northern and central Mexico.
