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 really is local to the eastern aspect of southern Africa, from Kenya south to South Africa, most varieties being within Cape Provinces. Types of the previous genus Anomatheca are now included in Freesia. The plants often called "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia species. Some other varieties are also expanded as ornamental plants.
They may be herbaceous plant life 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 blooms with six tepals. Many types have fragrant narrowly funnel-shaped bouquets, although those previously positioned in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera species including Large Yellow Underwing.
CULTIVATION AND USES
The plants usually called "freesias" derive 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 types of F. corymbosa. Modern tetraploid cultivars have blooms which range from white to yellow, red, red and blue-mauve. They may be mostly cultivated expertly in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Due to their specific and desirable scent, they are often used in palm ointments, shampoos, candles, etc.[citation needed], however, the plants are mainly used in wedding bouquets. They could be planted in the fall in USDA Hardiness Areas 9-10 (i.e. where the temperature will not show up 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 somewhat than cup-shaped plants. 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 formation of buds within a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal products) are vegetation which may have no prolonged woody stem above floor. Herbaceous plant life may be annuals, biennials or perennials. Total annual herbaceous plants expire completely by the end of the growing season or when they have flowered and fruited, and they then increase again from seed. Herbaceous perennial and biennial vegetation may have stems that pass away at the end of the growing season, but elements of the plant make it through under or near to the bottom from season to season (for biennials, until the next growing season, when they rose and pass away). New development grows from living tissues remaining on or under the bottom, including roots, a caudex (a thickened part of the stem at walk out) or numerous kinds of underground stems, such as lights, 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 vegetation are woody crops that have stems above earth that continue to be alive through the dormant season and increase shoots the next 12 months from the above-ground parts - these include trees and shrubs, shrubs and vines.
