Freesia is a genus of herbaceous perennial flowering plants 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 is local to the eastern side of southern Africa, from Kenya south to South Africa, most species being within Cape Provinces. Varieties of the former genus Anomatheca are now included in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia types. Some other varieties are also harvested as ornamental vegetation.
These are herbaceous crops which expand from a conical corm 1-2.5 cm diameter, which delivers up a tuft of small 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 bouquets with six tepals. Many species have fragrant narrowly funnel-shaped blooms, although those previously positioned in the genus Anomatheca, such as F. laxa, have level flowers. Freesias are being used as food crops by the larvae of some Lepidoptera kinds including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life 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 types and the pink- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have blossoms ranging from white to yellowish, pink, red and blue-mauve. They are really mostly cultivated properly in holland by about 80 growers.[3] Freesias can be commonly increased from seed. Because of their specific and pleasing scent, they are generally used in side products, shampoos, candles, etc.[citation needed], however, the blooms are mainly used in wedding bouquets. They can be planted in the fall in USDA Hardiness Zones 9-10 (i.e. where the temperature does 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 types of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it offers flat somewhat than cup-shaped blossoms. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy chilly dormancy which results in formation of buds in just a predicted volume of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply natural remedies) are vegetation that have no prolonged woody stem above ground. Herbaceous vegetation may be annuals, biennials or perennials. Total annual herbaceous plants pass away completely at the end of the growing season or when they have flowered and fruited, and they then develop again from seed. Herbaceous perennial and biennial plants may have stems that pass away at 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 flower and die). New development evolves from living cells left over on or under the ground, including origins, a caudex (a thickened portion of the stem at walk out) or various types of underground stems, such as light 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 & most grasses. By contrast, non-herbaceous perennial plant life are woody crops that have stems above ground that stay alive during the dormant season and develop shoots the next calendar year from the above-ground parts - these include trees, shrubs and vines.
