Packera plattensis, commonly known as prairie ragwort or prairie groundsel, is a species of the genus Packera and family Asteraceae. It used to be placed in the genus Senecio .

Prairie groundsel is found throughout the tallgrass prairie region. It blooms fairly early for a prairie wildflower: from April to July depending on the climate. [1]

It is easily confused with golden ragwort ( Packera aurea ) which has a hairless stem and heart-shaped basal leaves, and Senecio integerrimus , which has leaves that are mostly entire instead of fern-like, and much larger basal leaves. [2]

The cinnabar moth is a brightly coloured arctiid moth found as a native species in Europe and western and central Asia then east across the Palearctic to Siberia to China. It has been introduced into New Zealand, Australia and North America to control ragwort, on which its larvae feed. The moth is named after the red mineral cinnabar because of the red patches on its predominantly black wings. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Cinnabar moths are about 20 mm (0.79 in) long and have a wingspan of 32–42 mm (1.3–1.7 in).

<i>Packera</i> Genus of flowering plants in the family Asteraceae

Packera is a genus of about 75 species of plants in the daisy family, Asteraceae. Most species are commonly called ragworts or grounsels. Its members were previously included in the genus Senecio, but were moved to a different genus based on chromosome numbers, a variety of morphological characters, and molecular phylogenetic evidence.

<i>Packera obovata</i> Species of plant

Packera obovata, commonly known as roundleaf ragwort, spoon-leaved ragwort, roundleaf groundsel, or squaw-weed, is an erect perennial herb in the Asteraceae (aster) family native to eastern North America. It was previously called Senecio obovatus. Basal and lower leaves are obovate with toothed margins, while upper leaves are pinnately divided. The ray flowers are yellow and the disk flowers orange-yellow, the inflorescences being held well above the foliage.

<i>Senecio squalidus</i> Species of flowering plant in the daisy family Asteraceae

Senecio squalidus, known as Oxford ragwort, is a flowering plant in the daisy family Asteraceae. It is a yellow-flowered herbaceous plant, native to mountainous, rocky or volcanic areas, that has managed to find other homes on man-made and natural piles of rocks, war-ruined neighborhoods and even on stone walls. These habitats resemble its well drained natural rocky homeland. The plants have spread via the wind, rail and the activities of botanists. The travels of this short-lived perennial, biennial, or winter annual make it a good subject for studies of the evolution and ecology of flowering plants.

It is a biennial or perennial herb producing one or a few erect stems 20 to 70 centimeters tall from a caudex with fleshy shallow roots. The linear to lance-shaped or triangular leaves are primarily basal, with blades up to 25 cm (10 in) long. The herbage is slightly hairy to woolly or cobwebby. The inflorescence bears several flower heads in a cluster, the middle, terminal head often largest and held on a shorter peduncle, making the cluster look flat. The heads contain many disc florets and usually 8 or 13 ray florets which may be yellow to cream to white in color. Some heads lack ray florets.
