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 varieties being within Cape Provinces. Varieties of the former genus Anomatheca are now contained in Freesia. The crops often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of lots of Freesia kinds. Some other species are also produced as ornamental vegetation.
They are really herbaceous vegetation which expand from a conical corm 1-2.5 cm diameter, which delivers 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 kinds have fragrant narrowly funnel-shaped blooms, although those previously positioned in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera varieties including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" derive from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these varieties and the pink- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blooms ranging from white to yellow, green, red and blue-mauve. They are simply mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be commonly increased from seed. Because of the specific and desirable scent, they are generally used in palm creams, shampoos, candles, etc.[citation needed], however, the blooms are mainly utilized in wedding bouquets. They can be planted in the fall in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature will not land 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 varieties of the genus which is often cultivated. Smaller than the scented freesia cultivars, it offers flat somewhat than cup-shaped blooms. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the bulbs in proprietary solutions to satisfy cold dormancy which results in development of buds in a predicted volume of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply natural herbs) are vegetation which may have no consistent woody stem above ground. Herbaceous plants may be annuals, biennials or perennials. Total annual herbaceous plants expire completely at the end of the growing season or when they may have flowered and fruited, plus they then develop again from seed. Herbaceous perennial and biennial plants may have stems that die by the end of the growing season, but parts of the plant make it through under or near the bottom from season to season (for biennials, until the next growing season, when they bloom and die). New development develops from living tissue remaining on or under the bottom, including origins, a caudex (a thickened part of the stem at ground level) or numerous kinds of underground stems, such as light bulbs, 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. By contrast, non-herbaceous perennial plants are woody vegetation that have stems above surface that stay alive during the dormant season and develop shoots another calendar year from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
