Freesia is a genus of herbaceous perennial flowering vegetation in the family Iridaceae, first referred to 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 local to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Kinds of the previous genus Anomatheca are actually included in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of a number of Freesia varieties. Some other species are also produced as ornamental plant life.
They can be herbaceous vegetation which expand from a conical corm 1-2.5 cm diameter, which directs up a tuft of slim leaves 10-30 cm long, and a sparsely branched stem 10-40 cm extra tall bearing a few leaves and a loose one-sided spike of blossoms with six tepals. Many species have fragrant narrowly funnel-shaped bouquets, although those previously placed in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food plant life by the larvae of some Lepidoptera kinds including Large Yellow Underwing.
CULTIVATION AND USES
The crops usually called "freesias" are derived from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these varieties and the red- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have blooms ranging from white to yellowish, green, red and blue-mauve. They are really mostly cultivated properly in holland by about 80 growers.[3] Freesias can be readily increased from seed. Due to their specific and desirable scent, they are generally used in side creams, shampoos, candles, etc.[citation needed], however, the bouquets are mainly utilized in wedding bouquets. They can be planted in the land in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature does not fall season below about -7 ?C (20 ?F)), and in the spring in Areas 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other kinds of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it has flat rather 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 chilly dormancy which results in formation of buds within a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbal selections) are plants which may have no prolonged woody stem above ground. Herbaceous vegetation may be annuals, biennials or perennials. Annual herbaceous plants perish completely by the end of the growing season or when they have flowered and fruited, plus they then grow again from seed. Herbaceous perennial and biennial plant life may have stems that pass away at the end of the growing season, but parts of the plant survive under or near the ground from season to season (for biennials, before next growing season, when they flower and die). New development advances from living tissue remaining on or under the bottom, including roots, a caudex (a thickened portion of the stem at walk out) or numerous kinds of underground stems, such as light 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 vegetation are woody plant life that have stems above floor that continue to be alive through the dormant season and expand shoots the next 12 months from the above-ground parts - these include trees and shrubs, shrubs and vines.
