Vernonia
''Vernonia'' is a genus of about 350 species of forbs and shrubs in the Daisy family Asteraceae. Some species are known as ironweed. Some species are edible and of economic value. They are known for having intense purple flowers. There have been numerous distinct subgenera and subsections named in this genus, and some botanists have divided the genus into several distinct genera. For instance, the ''Flora of North America'' recognizes only about twenty species in ''Vernonia'' ''sensu stricto'', seventeen of which are in North America north of Mexico, with the others being found in South America. Taxonomy The genus was circumscribed by Johann Christian Daniel von Schreber in Gen. Pl. ed. 8 vol.2 on page 541 in 1791. The genus name of ''Vernonia'' is in honour of William Vernon (1666/67 - ca.1711), who was an English plant collector, ( bryologist) and entomologist from Cambridge University, who collected in Maryland, USA in 1698.

Vernonia Fasciculata
''Vernonia fasciculata'', the smooth ironweed or common ironweed, or prairie ironweed is a species of perennial plant from family Asteraceae. It is native to Manitoba in Canada and the north-central U.S.A. ''Vernonia fasciculata'' inhabits areas with moist soils and prairies. It flowers in July to September. Description ''Vernonia fasciculata'' is a herbaceous perennial that grows tall with unbranched stems, which end in an inflorescences with magenta flowers arranged in a dense corymb Corymb is a botanical term for an inflorescence with the flowers growing in such a fashion that the outermost are borne on longer pedicels than the inner, bringing all flowers up to a common level. A corymb has a flattish top with a superficial re .... Cultivation ''V. fasciculata'' is winter hardy in USDA zones 4-9, it is planted in full sun and used in rain gardens and as a naturalized plant because of its showy flower display, it is deer tolerant and adaptable to wet soils.

Vernonia Galamensis (25396105376)
''Vernonia galamensis'' is a plant in the sunflower family, known for its use as an oilseed. This species, often called ironweed, is the largest source of vernonia oil, which is rich in a useful epoxy fatty acid called vernolic acid and is used to make plastics, rubbery coatings, and drying agents. Use of this oil as a replacement for traditional plasticizers and binders in the production of paints and PVC shows promise as a method of reducing smog pollution. One of over 1,000 species in genus ''Vernonia'', ''V. galamensis'' is native to East Africa. It is grown in the region as an industrial oilseed. Its seed production is poor when it is grown outside of the equatorial region, so cultivation in other places is not always economically worthwhile; however, further studies in the breeding of this species to generate more productive varieties may show promise. It requires loose, porous soil and long periods of dry conditions. It is grown in many parts of Ethiopia, especially ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vernonia Baldwinii
''Vernonia baldwinii'', commonly known as western ironweed or Baldwin's ironweed, is a perennial herb native to the central United States. It is in the Asteraceae (aster) family.
