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 known as after German botanist and doctor Friedrich Freese (1794-1878). It is local to the eastern aspect of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Types of the past genus Anomatheca are actually included in Freesia. The plants often called "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of a number of Freesia species. Some other varieties are also produced as ornamental plant life.
They are really herbaceous vegetation which expand from a conical corm 1-2.5 cm size, which directs up a tuft of slim 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 types have fragrant narrowly funnel-shaped plants, although those previously put in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are being used as food crops by the larvae of some Lepidoptera varieties including Large Yellowish Underwing.
CULTIVATION AND USES
The crops 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 species and the pink- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have flowers ranging from white to yellowish, pink, red and blue-mauve. They are simply mostly cultivated expertly in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Because of their specific and satisfying scent, they are often used in hands ointments, shampoos, candles, etc.[citation needed], however, the blooms are mainly utilized in wedding bouquets. They could be planted in the fall season in USDA Hardiness Areas 9-10 (i.e. where the temperature will not show up 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 commonly cultivated. Smaller than the scented freesia cultivars, it offers flat rather than cup-shaped blooms. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy chilly dormancy which results in creation of buds within the predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbs) are vegetation that contain no consistent woody stem above floor. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants perish completely by the end of the growing season or when they have flowered and fruited, and they then develop again from seed. Herbaceous perennial and biennial vegetation may have stems that die by the end of the growing season, but parts of the plant endure under or close to the bottom from season to season (for biennials, before next growing season, when they blossom and die). New expansion builds up from living tissues left over on or under the bottom, including root base, a caudex (a thickened part of the stem at walk out) or various types of underground stems, such as lights, 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. By contrast, non-herbaceous perennial vegetation are woody plants which have stems above ground that remain alive through the dormant season and increase shoots the next yr from the above-ground parts - these include trees, shrubs and vines.
