Packera anonyma, called Appalachian ragwort and Small's ragwort, is a flowering plant in the Asteraceae (aster family). [1] [2] [3]
A perennial herb native to the lower Northeastern United States and across the Southeastern United States, [1] it is found in regions including the Appalachian Mountains and the southeastern Great Lakes states. [1] It inhabits rock outcrops, roadsides, woods, and disturbed areas. [3]
Packera anonyma produces abundant yellow flowers in May and early June. [1] [3] It blooms April to May in the South, and early June to mid-July in the North. [4]
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.
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.
Marshallia is a genus of plants in the tribe Helenieae within the family Asteraceae. Marshallia is native to the southeastern and south-central United States. A common name applied to most species in the genus is Barbara's buttons.
Packera aurea, commonly known as golden ragwort or simply ragwort, is a perennial flower in the family Asteraceae.
Senecio ampullaceus, also known as Texas ragwort, Texas squaw-weed, Texas groundsel, and Texas butterweed, is a species of Senecio in the family Asteraceae, receiving its Latin name ampullaceus from its flask shaped flower-head. It is recommended for landscape use in its native Texas.
Ragwort may refer to a number of plant species:
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.
Packera paupercula is a flowering plant species of the genus Packera and family Asteraceae, native to North America, where it is widespread across Canada and much of the United States. Its common names include balsam ragwort and balsam groundsel. It is a perennial herb that grows 1–3 feet tall. Its habitats include wet meadows, open woodlands, and rocky outcrops.
Packera antennariifolia, the shale barren ragwort, is a species of the genus Packera and family Asteraceae.
Packera bernardina is a rare species of flowering plant in the aster family known by the common name San Bernardino ragwort.
Packera bolanderi is a species of flowering plant in the aster family known by the common names Bolander's ragwort and seacoast ragwort. It is native to the west coast of the United States from Washington to northern California, where it grows in wet coastal forests and woodlands. There are two varieties of the species which differ slightly in morphology and habitat occupied; these varieties have been considered separate species by some authors. The var. bolanderi has thicker leaves, occurs farther south, and occupies more open types of habitat, than does var. harfordii. This plant in general is a perennial herb producing one to three stems up to half a meter tall. The basal leaves have blades up to 12 centimeters long which are divided into several lobes and borne on long, thin petioles. Leaves growing farther up the stem are smaller and have more lobes on their blades. The inflorescence contains several flower heads, each lined with dark green phyllaries. The head contains many golden yellow disc florets and generally either 8 or 13 yellow ray florets each over a centimeter long. The fruit is an achene tipped with a pappus of bristles.
Packera ganderi is a rare species of flowering plant in the aster family known by the common name Gander's ragwort. It is endemic to southern California, where it is known from a few occurrences in San Diego and Riverside Counties.
Packera layneae, known by the common name Layne's ragwort and Layne's butterweed, is a rare species of flowering plant in the aster family.
Packera franciscana is a rare species of flowering plant in the aster family known by the common name San Francisco Peaks groundsel, or San Francisco Peaks ragwort. It is endemic to Arizona in the United States, where it is known only from the San Francisco Peaks in Coconino County. It is threatened by recreational activities in its habitat. It is a federally listed threatened species of the United States.
Packera malmstenii is a rare species of flowering plant in the aster family known by the common name Podunk ragwort. It is endemic to Utah in the United States, where there about 19 occurrences in the southwestern part of the state.
Packera dubia, synonym Packera tomentosa, is a species of flowering plant in the composite family. It is known by the common name woolly ragwort. It is native to the Southeastern United States, primarily to the coastal plain but extending into some areas inland. Its preferred habitat is open, sandy areas and granitic outcrops. It is common throughout its range.
Packera cardamine is a species of flowering plant in the aster family known by the common name bittercress ragwort.
Woolly ragwort is a common name for several plants and may refer to:
Packera serpenticola, commonly known as serpentine ragwort, is a species of flowering plant in the composite family.
Packera schweinitziana, commonly called New England groundsel, is a species of flowering plant in the aster family (Asteraceae). It is native to eastern North America, where it is primarily found in eastern Canada and the northeastern United States, with disjunct populations in North Carolina and Tennessee on Roan Mountain. Its natural habitat is in sunny, wet areas, often in acidic soil. In the southeastern United States, its habitat is restricted to Appalachian balds.
