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 known as after German botanist and doctor Friedrich Freese (1794-1878). It really is native to the eastern part of southern Africa, from Kenya south to South Africa, most varieties being found in Cape Provinces. Species 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 lots of Freesia species. Some other types are also harvested as ornamental plant life.
These are herbaceous crops which expand from a conical corm 1-2.5 cm diameter, which transmits up a tuft of thin leaves 10-30 cm long, and a sparsely branched stem 10-40 cm high bearing a few leaves and a loose one-sided spike of bouquets with six tepals. Many varieties have fragrant narrowly funnel-shaped blooms, although those previously put in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are being used as food plants 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 varieties and the red- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellow, green, red and blue-mauve. They can be mostly cultivated professionally in the Netherlands by about 80 growers.[3] Freesias can be quickly increased from seed. Because of the specific and satisfying scent, they are often used in hand ointments, shampoos, candles, etc.[citation needed], however, the bouquets are mainly used in wedding bouquets. They can be planted in the fall season in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature will not fall below about -7 ?C (20 ?F)), and in the spring in Areas 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other species of the genus which is often cultivated. Smaller than the scented freesia cultivars, they have flat rather 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 solutions to satisfy frosty dormancy which results in development of buds within a predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply natural herbs) are plant life which may have no consistent woody stem above floor. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants perish 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 vegetation may have stems that die by the end of the growing season, but elements of the plant survive under or near the bottom from season to season (for biennials, until the next growing season, when they rose and die). New development develops from living tissues left over on or under the ground, including root base, a caudex (a thickened portion of the stem at ground level) or numerous kinds 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 plants are woody crops which have stems above earth that remain alive through the dormant season and increase shoots another calendar year from the above-ground parts - these include trees, shrubs and vines.
