Freesia is a genus of herbaceous perennial flowering plants 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 local to the eastern area of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Varieties of the ex - genus Anomatheca are actually contained in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of a number of Freesia varieties. Some other varieties are also expanded as ornamental vegetation.
They can be herbaceous crops which increase from a conical corm 1-2.5 cm diameter, which directs 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 varieties have fragrant narrowly funnel-shaped plants, although those previously located in the genus Anomatheca, such as F. laxa, have level flowers. Freesias are used as food plants by the larvae of some Lepidoptera types including Large Yellow Underwing.
CULTIVATION AND USES
The plants usually called "freesias" are derived from crosses made in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the green- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellowish, red, red and blue-mauve. They may be mostly cultivated appropriately in holland by about 80 growers.[3] Freesias can be commonly increased from seed. Because of the specific and satisfying scent, they are generally used in hands creams, shampoos, candles, etc.[citation needed], however, the bouquets are mainly utilized in wedding bouquets. They can be planted in the show up in USDA Hardiness Areas 9-10 (i.e. where the temperature will not fall 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 varieties of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat alternatively than cup-shaped blossoms. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the lights in proprietary methods to satisfy cool dormancy which results in formation of buds within the predicted amount of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply natural remedies) are vegetation which have no continual woody stem above ground. Herbaceous vegetation may be annuals, biennials or perennials. Annual herbaceous plants pass away completely by the end of the growing season or when they may have flowered and fruited, and they then increase again from seed. Herbaceous perennial and biennial plants may have stems that pass away at the end of the growing season, but elements of the plant endure under or near to the ground from season to season (for biennials, before next growing season, when they rose and perish). New expansion builds up from living tissue left over on or under the ground, including roots, 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 plants are woody plants that have stems above surface that continue to be alive through the dormant season and grow shoots another season from the above-ground parts - included in these are trees, shrubs and vines.
