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 named after German botanist and doctor Friedrich Freese (1794-1878). It really is native to the eastern area of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Kinds of the past genus Anomatheca are now contained in Freesia. The plants often called "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of a number of Freesia kinds. Some other types are also cultivated as ornamental plants.
They can be herbaceous vegetation which expand from a conical corm 1-2.5 cm size, which delivers up a tuft of small 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 species have fragrant narrowly funnel-shaped blossoms, although those previously positioned in the genus Anomatheca, such as F. laxa, have level flowers. Freesias are used as food plants by the larvae of some Lepidoptera species including Large Yellowish Underwing.
CULTIVATION AND USES
The plants usually called "freesias" are derived from crosses manufactured in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the pink- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blooms which range from white to yellow, red, red and blue-mauve. They can be mostly cultivated appropriately in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Because of the specific and attractive scent, they are generally used in hand products, shampoos, candles, etc.[citation needed], however, the plants are mainly used in wedding bouquets. They could be planted in the land in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature does not land below about -7 ?C (20 ?F)), and in the springtime in Zones 4-8.
Freesia laxa (formerly 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 offers flat rather than cup-shaped bouquets. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy frosty dormancy which results in formation of buds in just a predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply herbal selections) are crops that contain no continual woody stem above ground. Herbaceous plants may be annuals, biennials or perennials. Total annual herbaceous plants pass away completely at the end of the growing season or when they have flowered and fruited, and they then expand again from seed. Herbaceous perennial and biennial plant life may have stems that die at the end of the growing season, but elements of the plant survive under or near the bottom from season to season (for biennials, before next growing season, when they blossom and perish). New development evolves from living cells remaining on or under the ground, including roots, a caudex (a thickened portion 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. In comparison, non-herbaceous perennial plant life are woody plants that have stems above ground that continue to be alive during the dormant season and develop shoots another calendar year from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
