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. Types of the previous genus Anomatheca are actually contained in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of Freesia kinds. Some other types are also grown up as ornamental plant life.
They can be herbaceous plant life which develop from a conical corm 1-2.5 cm size, which transmits up a tuft of narrow 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 bouquets with six tepals. Many varieties have fragrant narrowly funnel-shaped plants, although those previously put in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are being used as food crops by the larvae of some Lepidoptera kinds including Large Yellowish Underwing.
CULTIVATION AND USES
The plants 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 kinds and the green- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have blooms ranging from white to yellowish, red, red and blue-mauve. They are really mostly cultivated skillfully in the Netherlands by about 80 growers.[3] Freesias can be commonly increased from seed. Due to their specific and pleasing scent, they are often used in hand creams, shampoos, candles, etc.[citation needed], however, the bouquets are mainly utilized in wedding bouquets. They could be planted in the land in USDA Hardiness Areas 9-10 (i.e. where the temperature does not fall season below about -7 ?C (20 ?F)), and in the springtime in Areas 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other types of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat somewhat than cup-shaped blossoms. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy chilly dormancy which results in development of buds in a predicted quantity of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbs) are crops that contain no prolonged woody stem above floor. Herbaceous plants may be annuals, biennials or perennials. Annual herbaceous plants expire completely at the end of the growing season or when they have flowered and fruited, plus they then increase again from seed. Herbaceous perennial and biennial plants may have stems that pass away by the end of the growing season, but elements of the plant survive under or near the ground from season to season (for biennials, until the next growing season, when they blossom and perish). New expansion builds up from living tissue staying on or under the ground, including root base, a caudex (a thickened part of the stem at ground level) 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 and most grasses. By contrast, non-herbaceous perennial plants are woody crops that 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 and shrubs, shrubs and vines.
