Senecio pygmaeus, the pygmy ragwort, is a species of plant in the Asteraceae family. It is sub-endemic to Malta, it also found in Sicily, Lampedusa, Pantelleria, and other islands. [1]
Senecio is a genus of flowering plants in the daisy family (Asteraceae) that includes ragworts and groundsels. The scientific name, Senecio, means "old man".
Jacobaea vulgaris, syn. Senecio jacobaea, is a very common wild flower in the family Asteraceae that is native to northern Eurasia, usually in dry, open places, and has also been widely distributed as a weed elsewhere.
Senecio vulgaris, often known by the common names groundsel and old-man-in-the-spring, is a flowering plant in the daisy family Asteraceae. It is an annual herb, native to Europe and widely naturalised as a ruderal species in suitable disturbed habitats worldwide.
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).
Packera is a genus of about 64 species of plants in the composite family, Asteraceae. Its members were previously included in the genus Senecio, but were divided out based on chromosome numbers, a variety of morphological characters, and molecular phylogeny.
Jacobaea maritima, commonly known as silver ragwort, is a perennial plant species in the genus Jacobaea in the family Asteraceae, native to the Mediterranean region. It was formerly placed in the genus Senecio, and is still widely referred to as Senecio cineraria; see the list of synonyms (right) for other names.
Packera aurea, commonly known as golden ragwort or simply ragwort, is a perennial flower in the family Asteraceae. It is also known as golden groundsel, squaw weed, life root, golden Senecio, uncum, uncum root, waw weed, false valerian, cough weed, female regulator, cocash weed, ragweed, staggerwort, and St. James wort.
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.
Ragwort may refer to a number of plant species:
Senecio flaccidus, formerly recorded as Senecio douglasii, member of the daisy family and genus Senecio also known as threadleaf ragwort, is a native of the southwestern Great Plains of North America.
Senecio congestus, also known by its common names swamp ragwort, northern swamp groundsel, marsh fleabane, marsh fleawort, clustered marsh ragwort and mastodon flower, a herbaceous member of the family Asteraceae and the genus Senecio, can be seen most easily when its bright yellow umbel flowers appear from May to early July standing 3 to 4 feet along marshes, stream banks and slough areas where it likes to grow.
Senecio leucanthemifolius is a plant common in sea-side in Mediterranean area.
Senecio fremontii, the dwarf mountain ragwort, is a species of the genus Senecio and family Asteraceae. It takes its scientific name from John C. Frémont.
Senecio aphanactis, known by the common names chaparral ragwort, rayless ragwort, and California groundsel, is a species of flowering plant in the aster family.
Senecio mohavensis, known by the common name Mojave ragwort, is a species of flowering plant in the aster family.
Senecio pattersonensis is an uncommon species of flowering plant in the aster family known by the common names Mono ragwort. and Mount Patterson senecio.
Senecio glastifolius is a species of flowering plant in the aster family known by the common names woad-leaved ragwort, holly-leaved senecio, and pink ragwort. A tall perennial herb, it is native to southern Africa, and it is cultivated as an ornamental plant for its colorful flowers. It has been known to escape cultivation and become naturalized in areas of appropriate climate; it can be found growing wild in parts of New Zealand and Australia.
Senecio bigelovii or nodding groundsel or nodding ragwort is a perennial herb native to the Colorado Plateau region of the United States.
