Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first described as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and named 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. Species of the ex - genus Anomatheca are now contained in Freesia. The plants often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of a number of Freesia species. Some other species are also grown up as ornamental crops.
They may be herbaceous vegetation which grow from a conical corm 1-2.5 cm size, which directs up a tuft of slim leaves 10-30 cm long, and a sparsely branched stem 10-40 cm tall bearing a few leaves and a loose one-sided spike of bouquets with six tepals. Many types have fragrant narrowly funnel-shaped blooms, although those formerly placed in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are used as food plant life by the larvae of some Lepidoptera species including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life 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 red- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellow, pink, red and blue-mauve. They can be mostly cultivated properly in holland by about 80 growers.[3] Freesias can be immediately increased from seed. Because of the specific and attractive scent, they are often used in palm products, shampoos, candles, etc.[citation needed], however, the flowers 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 will not fall season below about -7 ?C (20 ?F)), and in the spring in Areas 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other types of the genus which is often cultivated. Smaller than the scented freesia cultivars, it has flat somewhat than cup-shaped blossoms. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the light bulbs in proprietary methods to satisfy cold dormancy which results in development of buds within the predicted volume of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply herbal selections) are plants that contain no consistent woody stem above floor. Herbaceous plants may be annuals, biennials or perennials. Annual herbaceous plants pass away completely at the end of the growing season or when they have flowered and fruited, and they then grow again from seed. Herbaceous perennial and biennial plant life may have stems that pass away at the end of the growing season, but parts of the plant survive under or near the bottom from season to season (for biennials, until the next growing season, when they bloom and perish). New development evolves from living tissue left over on or under the bottom, including origins, a caudex (a thickened part of the stem at walk out) or various types of underground stems, such as 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. In comparison, non-herbaceous perennial vegetation are woody crops which have stems above earth that stay alive through the dormant season and develop shoots another 12 months from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
