Packera dubia, synonym Packera tomentosa, is a species of flowering plant in the composite family. [1] 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. [2] Its preferred habitat is open, sandy areas and granitic outcrops. It is common throughout its range. [3]
Packera dubia is a perennial that produces a head of yellow flowers in late spring. Its seeds have been shown to have varying masses within a single head of flowers, perhaps as an adaptation for better dispersal in disturbed habitats. [4]
Paulownia tomentosa, common names princess tree, empress tree, or foxglove-tree, is a deciduous hardwood tree in the family Paulowniaceae, native to central and eastern China and the Korean Peninsula. It is an extremely fast-growing tree with seeds that disperse readily and is considered an invasive exotic species in North America that has undergone naturalisation in large areas of the Eastern US, even though it might be able to successfully get established through seeds only under ideal conditions. P. tomentosa has also been introduced to Western and Central Europe, and is establishing itself as a naturalised species there as well.
Digitalis purpurea, the foxglove or common foxglove, is a toxic species of flowering plant in the plantain family Plantaginaceae, native to and widespread throughout most of temperate Europe. It has also naturalized in parts of North America, as well as some other temperate regions. The plant is a popular garden subject, with many cultivars available. It is the original source of the heart medicine digoxin. This biennial plant grows as a rosette of leaves in the first year after sowing, before flowering and then dying in the second year. It generally produces enough seeds so that new plants will continue to grow in a garden setting.
Rhodomyrtus tomentosa also known as rose myrtle, is a flowering plant in the family Myrtaceae, native to southern and southeastern Asia, from India, east to southern China, Hong Kong, Taiwan and the Philippines, and south to Malaysia and Sulawesi. It grows in coasts, natural forest, riparian zones, wetlands, moist and wet forests, bog margins, from sea level up to 2400 m elevation.
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, or roundleaf groundsel 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.
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 eurycephala is a species of flowering plant in the aster family known by the common name widehead groundsel. It is native to a section of the western United States encompassing southern Oregon, northern California, and northern Nevada. It can be found in dry habitat types, often in disturbed areas, and it favors serpentine soils.
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 multilobata is a species of flowering plant in the aster family known by the common name lobeleaf groundsel. It is native to the western United States from California to Wyoming to New Mexico, where it is common and can be found in many habitat types.
Pulsatilla nuttalliana, known as American pasqueflower, prairie pasqueflower, prairie crocus, or simply pasqueflower, is a flowering plant native to much of North America, from the western side of Lake Michigan, to northern Canada in the Northwest Territories, south to New Mexico in the southwestern United States. Pasqueflower is the provincial flower of Manitoba and the state flower of South Dakota.
Erythranthe michiganensis is a rare species of flowering plant in the lopseed family, known by the common name Michigan monkeyflower. This species occurs only in the Grand Traverse and Mackinac Straits areas within the American state of Michigan. It is one of only three plant species that are endemic to Michigan, with the other two being Voss's Goldenrod and Packera insulae-regalis.
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 castoreus is a rare species of flowering plant in the aster family known by the common names Beaver Mountain groundsel and Beaver Mountain ragwort. It is endemic to Utah in the United States, where it occurs only in the Tushar Mountains.
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.
Gaylussacia frondosa is a species of flowering plant in the heath family known by the common names dangleberry and blue huckleberry. It is native to the eastern United States, where it occurs from New Hampshire to South Carolina.
Phacelia dubia is an annual forb native to the eastern United States, that produces cream colored or light blue flowers in early spring.
Woolly ragwort is a common name for several plants and may refer to:
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.
Casearia tomentosa, commonly known as the toothed leaf chilla, is a species of flowering plant in the family Salicaceae, native to the Indian Subcontinent and Myanmar. It is one of 1,000 species that can be found in the Salicaeceae family. Casearia tomentosa has various phytochemical and pharmacological properties that are used in traditional medicine preparations said to be helpful for many illnesses. It is most notably sold to people who suffer from seafood poisoning, diabetes, ringworm, and snake bites. Other common names include Bhari, Maun, Churcha, Sonne bethe, and Kakoli based on the region where it is found.
