Freesia is a genus of herbaceous perennial flowering plant life in the family Iridaceae, first referred to 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 aspect of southern Africa, from Kenya south to South Africa, most types being found in Cape Provinces. Varieties of the ex - genus Anomatheca are actually included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of lots of Freesia types. Some other types are also harvested as ornamental crops.
They are really herbaceous plants which increase from a conical corm 1-2.5 cm diameter, which sends up a tuft of thin 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 plants with six tepals. Many varieties have fragrant narrowly funnel-shaped plants, although those formerly positioned in the genus Anomatheca, such as F. laxa, have level flowers. Freesias are used as food plant life by the larvae of some Lepidoptera species including Large Yellow Underwing.
CULTIVATION AND USES
The plant life 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 green- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blooms which range from white to yellowish, green, red and blue-mauve. They are mostly cultivated appropriately in holland by about 80 growers.[3] Freesias can be quickly increased from seed. Because of the specific and attractive scent, they are generally used in palm creams, shampoos, candles, etc.[citation needed], however, the flowers are mainly used in wedding bouquets. They could be planted in the fall in USDA Hardiness Zones 9-10 (i.e. where the temperature does not land below about -7 ?C (20 ?F)), and in the springtime 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 includes flat rather than cup-shaped bouquets. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary solutions 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 herbal selections) are vegetation that contain no prolonged woody stem above surface. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants perish 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 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, until the next growing season, when they blossom and pass away). New growth produces from living cells left over on or under the ground, including roots, a caudex (a thickened part of the stem at walk out) or numerous kinds of underground stems, such as bulbs, corms, stolons, rhizomes and tubers. Types 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 vegetation that have stems above surface that remain alive through the dormant season and expand shoots another calendar year from the above-ground parts - these include trees and shrubs, shrubs and vines.
