Freesia is a genus of herbaceous perennial flowering plant life in the family Iridaceae, first described as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and called after German botanist and doctor Friedrich Freese (1794-1878). It really is local to the eastern part of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Varieties of the previous genus Anomatheca are actually included in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of a number of Freesia kinds. Some other varieties are also produced as ornamental vegetation.
These are herbaceous plants which expand from a conical corm 1-2.5 cm diameter, which sends up a tuft of slim leaves 10-30 cm long, and a sparsely branched stem 10-40 cm extra tall bearing a few leaves and a loose one-sided spike of bouquets with six tepals. Many species have fragrant narrowly funnel-shaped bouquets, although those previously located in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are used as food plant life by the larvae of some Lepidoptera types including Large Yellow Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" derive from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the pink- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have plants which range from white to yellow, pink, red and blue-mauve. They are mostly cultivated properly in holland by about 80 growers.[3] Freesias can be quickly increased from seed. Because of their specific and pleasing scent, they are often used in palm creams, shampoos, candles, etc.[citation needed], however, the blossoms are mainly utilized in wedding bouquets. They could be planted in the fall season in USDA Hardiness Areas 9-10 (i.e. where the temperature will not fall below about -7 ?C (20 ?F)), and in the springtime in Areas 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other kinds of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it has flat somewhat than cup-shaped plants. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the lights in proprietary methods to satisfy chilly dormancy which results in formation of buds in just a predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal selections) are vegetation which may have no consistent woody stem above surface. Herbaceous vegetation may be annuals, biennials or perennials. Annual herbaceous plants die completely by the end of the growing season or when they may have flowered and fruited, plus they then develop again from seed. Herbaceous perennial and biennial crops may have stems that pass away by the end of the growing season, but elements of the plant survive under or near the bottom from season to season (for biennials, before next growing season, when they blossom and perish). New expansion builds up from living cells remaining on or under the ground, including root base, a caudex (a thickened part of the stem at ground level) or numerous kinds of underground stems, such as light bulbs, corms, stolons, rhizomes and tubers. Examples of herbaceous biennials include carrot, parsnip and common ragwort; herbaceous perennials include potato, peony, hosta, mint, most ferns and most grasses. By contrast, non-herbaceous perennial vegetation are woody plants that have stems above ground that continue to be alive through the dormant season and develop shoots another 12 months from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
