Freesia is a genus of herbaceous perennial flowering vegetation 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 is indigenous to the eastern part of southern Africa, from Kenya south to South Africa, most species being within Cape Provinces. Kinds of the ex - genus Anomatheca are actually contained in Freesia. The crops often called "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of lots of Freesia types. Some other varieties are also grown up as ornamental plant life.
They may be herbaceous crops which expand from a conical corm 1-2.5 cm diameter, which directs up a tuft of slim leaves 10-30 cm long, and a sparsely branched stem 10-40 cm tall bearing a few leaves and a loose one-sided spike of blooms with six tepals. Many kinds have fragrant narrowly funnel-shaped flowers, although those formerly positioned in the genus Anomatheca, such as F. laxa, have toned flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera varieties including Large Yellow Underwing.
CULTIVATION AND USES
The crops usually called "freesias" derive from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the red- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have blossoms which range from white to yellow, green, red and blue-mauve. They can be mostly cultivated properly in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Because of their specific and satisfying scent, they are generally used in palm creams, shampoos, candles, etc.[citation needed], however, the plants are mainly utilized in wedding bouquets. They could be planted in the land in USDA Hardiness Zones 9-10 (i.e. where the temperature will not land below about -7 ?C (20 ?F)), and in the spring in Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other types of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it includes flat alternatively than cup-shaped plants. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy wintry dormancy which results in development of buds within the predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbs) are plants which have no prolonged woody stem above earth. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants expire completely by the end of the growing season or when they may have flowered and fruited, plus they then grow 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, before next growing season, when they blossom and die). New development advances from living tissue staying on or under the bottom, including origins, a caudex (a thickened portion of the stem at walk out) or various types 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 & most grasses. In comparison, non-herbaceous perennial plant life are woody vegetation that have stems above ground that continue to be alive during the dormant season and expand shoots the next time from the above-ground parts - these include trees and shrubs, shrubs and vines.
