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 known as after German botanist and doctor Friedrich Freese (1794-1878). It really is indigenous to the eastern part of southern Africa, from Kenya south to South Africa, most kinds being within Cape Provinces. Kinds of the previous genus Anomatheca are actually included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of a number of Freesia types. Some other kinds are also grown as ornamental crops.
They are really herbaceous crops which develop from a conical corm 1-2.5 cm size, which delivers up a tuft of thin 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 kinds have fragrant narrowly funnel-shaped plants, although those formerly put in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are being used as food crops by the larvae of some Lepidoptera kinds including Large Yellowish Underwing.
CULTIVATION AND USES
The vegetation 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 red- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellowish, pink, red and blue-mauve. They are simply mostly cultivated professionally in the Netherlands by about 80 growers.[3] Freesias can be easily increased from seed. Because of the specific and attractive scent, they are generally used in palm ointments, shampoos, candles, etc.[citation needed], however, the blooms are mainly used in wedding bouquets. They could be planted in the street to redemption in USDA Hardiness Areas 9-10 (i.e. where the temperature will not fall 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 species of the genus which is often cultivated. Smaller than the scented freesia cultivars, it offers flat rather than cup-shaped bouquets. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the light bulbs in proprietary solutions to satisfy chilly dormancy which results in creation of buds in a predicted volume of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply natural remedies) are plants which have no prolonged woody stem above surface. Herbaceous plant life may be annuals, biennials or perennials. Annual herbaceous plants die completely at the end of the growing season or when they have got flowered and fruited, and 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 elements of the plant survive under or close to the bottom from season to season (for biennials, until the next growing season, when they flower and perish). New growth advances from living cells left over on or under the bottom, 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 & most grasses. In comparison, non-herbaceous perennial crops are woody plant life that have stems above ground that stay alive through the dormant season and expand shoots the next time from the above-ground parts - these include trees and shrubs, shrubs and vines.
