Freesia is a genus of herbaceous perennial flowering crops in the family Iridaceae, first described as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and known as after German botanist and doctor Friedrich Freese (1794-1878). It is indigenous to the eastern area of southern Africa, from Kenya south to South Africa, most varieties being within Cape Provinces. Varieties of the past genus Anomatheca are actually included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia kinds. Some other kinds are also grown up as ornamental plants.
They are simply herbaceous vegetation which grow from a conical corm 1-2.5 cm diameter, which delivers up a tuft of thin leaves 10-30 cm long, and a sparsely branched stem 10-40 cm large bearing a few leaves and a loose one-sided spike of flowers with six tepals. Many kinds have fragrant narrowly funnel-shaped blooms, although those formerly positioned in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food crops by the larvae of some Lepidoptera kinds including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" are derived from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these varieties and the pink- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have bouquets ranging from white to yellow, red, red and blue-mauve. They are mostly cultivated properly in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Because of the specific and pleasing scent, they are generally used in side creams, shampoos, candles, etc.[citation needed], however, the flowers are mainly utilized in wedding bouquets. They could be planted in the land in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature does not fall below about -7 ?C (20 ?F)), and in the spring and coil in Zones 4-8.
Freesia laxa (previously 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 includes flat somewhat than cup-shaped blooms. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the light bulbs in proprietary methods to satisfy wintry dormancy which results in creation of buds in a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbs) are plant life that have no continual woody stem above earth. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants perish completely at the end of the growing season or when they have got flowered and fruited, and they then develop again from seed. Herbaceous perennial and biennial vegetation may have stems that pass away at the end of the growing season, but parts of the plant make it through under or near to the ground from season to season (for biennials, until the next growing season, when they blossom and pass away). New progress grows from living tissues remaining on or under the bottom, including root base, a caudex (a thickened part of the stem at walk out) or numerous kinds of underground stems, such as 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 crops are woody vegetation which have stems above surface that stay alive during the dormant season and grow shoots the next season from the above-ground parts - these include trees and shrubs, shrubs and vines.
