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 is indigenous to the eastern side of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Species of the previous genus Anomatheca are actually contained in Freesia. The plants often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of a number of Freesia species. Some other types are also grown up as ornamental plant life.
They are really herbaceous vegetation which increase from a conical corm 1-2.5 cm size, which delivers up a tuft of slim leaves 10-30 cm long, and a sparsely branched stem 10-40 cm tall bearing a few leaves and a loose one-sided spike of bouquets with six tepals. Many species have fragrant narrowly funnel-shaped plants, although those previously placed in the genus Anomatheca, such as F. laxa, have flat 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 manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the red- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have blooms ranging from white to yellow, green, red and blue-mauve. They can be mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Due to their specific and satisfying scent, they are often used in side lotions, shampoos, candles, etc.[citation needed], however, the flowers are mainly utilized in wedding bouquets. They can be planted in the fall season in USDA Hardiness Zones 9-10 (i.e. where the temperature does not fall season below about -7 ?C (20 ?F)), and in the springtime in Zones 4-8.
Freesia laxa (previously 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 has flat alternatively than cup-shaped blooms. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary methods to satisfy frigid dormancy which results in formation of buds in just a predicted volume of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal remedies) are plants that have no prolonged woody stem above surface. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants expire completely at the end of the growing season or when they have got flowered and fruited, plus they then develop again from seed. Herbaceous perennial and biennial plant life may have stems that pass away by the end of the growing season, but parts of the plant make it through under or near to the bottom from season to season (for biennials, until the next growing season, when they rose and perish). New growth advances from living tissue remaining on or under the ground, including origins, 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. In comparison, non-herbaceous perennial plants are woody crops that have stems above surface that stay alive during the dormant season and develop shoots another season from the above-ground parts - included in these are trees, shrubs and vines.
