Freesia is a genus of herbaceous perennial flowering crops in the family Iridaceae, first referred to 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 side of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Types of the past genus Anomatheca are now contained in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of a number of Freesia species. Some other varieties are also produced as ornamental plant life.

They are herbaceous vegetation which develop from a conical corm 1-2.5 cm size, which transmits up a tuft of narrow 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 blossoms with six tepals. Many kinds have fragrant narrowly funnel-shaped bouquets, although those previously put in the genus Anomatheca, such as F. laxa, have chiseled flowers. Freesias are used as food crops by the larvae of some Lepidoptera types including Large Yellow Underwing.

CULTIVATION AND USES

The vegetation usually called "freesias" derive from crosses manufactured in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these species and the green- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have plants which range from white to yellowish, green, red and blue-mauve. They may be mostly cultivated appropriately in holland by about 80 growers.[3] Freesias can be conveniently 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 used in wedding bouquets. They can be planted in the semester in USDA Hardiness Zones 9-10 (i.e. where the temperature will not fall season below about -7 ?C (20 ?F)), and in the planting season in Areas 4-8.

Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other varieties of the genus which is often 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 wintry dormancy which results in development of buds in a predicted amount of weeks - often 5 weeks at 55 ?F (13 ?C).

Herbaceous plant life (in botanical use frequently simply herbs) are plant life which have no continual woody stem above earth. Herbaceous plants may be annuals, biennials or perennials. Annual herbaceous plants expire completely by the end of the growing season or when they have got flowered and fruited, and they then increase again from seed. Herbaceous perennial and biennial plants may have stems that die by the end of the growing season, but parts of the plant make it through under or near to the bottom from season to season (for biennials, until the next growing season, when they bloom and die). New progress builds up from living tissues left over on or under the ground, including origins, a caudex (a thickened portion of the stem at ground level) or various types of underground stems, such as bulbs, corms, stolons, rhizomes and tubers. Types of herbaceous biennials include carrot, parsnip and common ragwort; herbaceous perennials include potato, peony, hosta, mint, most ferns & most grasses. By contrast, non-herbaceous perennial vegetation are woody vegetation that have stems above surface that continue to be alive during the dormant season and grow shoots another 12 months from the above-ground parts - these include trees and shrubs, shrubs and vines.
