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 known as after German botanist and doctor Friedrich Freese (1794-1878). It is local to the eastern part of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Types of the past genus Anomatheca are actually contained in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of lots of Freesia kinds. Some other kinds are also cultivated as ornamental vegetation.
They are herbaceous crops 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 large bearing a few leaves and a loose one-sided spike of bouquets with six tepals. Many species have fragrant narrowly funnel-shaped flowers, although those previously placed in the genus Anomatheca, such as F. laxa, have chiseled flowers. Freesias are used as food vegetation by the larvae of some Lepidoptera species including Large Yellow Underwing.
CULTIVATION AND USES
The crops usually called "freesias" are derived from crosses manufactured in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the green- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have plants ranging from white to yellowish, green, red and blue-mauve. They are mostly cultivated appropriately in holland by about 80 growers.[3] Freesias can be immediately increased from seed. Because of their specific and desirable scent, they are often used in palm lotions, shampoos, candles, etc.[citation needed], however, the blossoms are mainly used in wedding bouquets. They could be planted in the show up in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature does not land below about -7 ?C (20 ?F)), and in the spring and coil in Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other varieties of the genus which is often cultivated. Smaller than the scented freesia cultivars, it offers flat alternatively than cup-shaped bouquets. 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 inside a predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply natural remedies) are vegetation which have no consistent woody stem above floor. 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, and they then expand 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 make it through under or near the ground from season to season (for biennials, until the next growing season, when they flower and pass away). New growth grows from living tissue staying on or under the ground, including root base, a caudex (a thickened portion of the stem at ground level) 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 & most grasses. By contrast, non-herbaceous perennial crops are woody crops which have stems above surface that continue to be alive through the dormant season and increase shoots another season from the above-ground parts - these include trees and shrubs, shrubs and vines.
