Freesia is a genus of herbaceous perennial flowering crops 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 indigenous to the eastern aspect of southern Africa, from Kenya south to South Africa, most varieties being found in Cape Provinces. Types of the previous genus Anomatheca are actually contained in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of lots of Freesia species. Some other species are also harvested as ornamental plant life.
They can be herbaceous plants which grow from a conical corm 1-2.5 cm size, which transmits up a tuft of narrow 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 blossoms with six tepals. Many types have fragrant narrowly funnel-shaped blooms, although those formerly put in the genus Anomatheca, such as F. laxa, have chiseled flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera types including Large Yellow Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" derive from crosses made in the 19th century 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 blooms which range from white to yellow, green, red and blue-mauve. These are mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be immediately increased from seed. Due to their specific and pleasing scent, they are generally used in hand lotions, shampoos, candles, etc.[citation needed], however, the blooms are mainly utilized in wedding bouquets. They can be planted in the street to redemption in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature will not fall 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 kinds of the genus which is often cultivated. Smaller than the scented freesia cultivars, it has flat somewhat than cup-shaped blooms. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the light bulbs in proprietary methods to satisfy frigid dormancy which results in development of buds within a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbal selections) are plant life which may have no continual woody stem above floor. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants die 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 plants may have stems that die by the end of the growing season, but parts of the plant endure under or near the bottom from season to season (for biennials, before next growing season, when they flower and pass away). New development evolves from living tissue staying on or under the ground, including root base, a caudex (a thickened part 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. In comparison, non-herbaceous perennial plant life are woody plant life which have stems above floor that remain alive through the dormant season and develop shoots the next yr from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
