Freesia is a genus of herbaceous perennial flowering plant life in the family Iridaceae, first described as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and called after German botanist and doctor Friedrich Freese (1794-1878). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Varieties of the former genus Anomatheca are now included in Freesia. The crops commonly known as "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia kinds. Some other kinds are also produced as ornamental plant life.
They can be herbaceous plant life which expand from a conical corm 1-2.5 cm size, which directs 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 blooms with six tepals. Many types have fragrant narrowly funnel-shaped bouquets, although those formerly positioned in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are being used as food plants by the larvae of some Lepidoptera varieties including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" are derived from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the pink- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellowish, pink, red and blue-mauve. They can be mostly cultivated properly in holland by about 80 growers.[3] Freesias can be readily increased from seed. Due to their specific and satisfying scent, they are often used in side products, shampoos, candles, etc.[citation needed], however, the plants are mainly used in wedding bouquets. They can be planted in the land in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature does not land 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 varieties of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat rather than cup-shaped flowers. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy cool dormancy which results in creation of buds within the predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbal products) are plant life that contain no consistent woody stem above earth. Herbaceous plant life may be annuals, biennials or perennials. Total annual herbaceous plants pass away completely by the end of the growing season or when they have got flowered and fruited, plus they then expand again from seed. Herbaceous perennial and biennial vegetation may have stems that die at the end of the growing season, but elements of the plant endure under or close to the bottom from season to season (for biennials, before next growing season, when they bloom and pass away). New expansion develops from living tissues remaining on or under the ground, including root base, a caudex (a thickened part of the stem at ground level) 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 and most grasses. In comparison, non-herbaceous perennial crops are woody plant life which have stems above ground that remain alive through the dormant season and expand shoots the next season from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
