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 known as after German botanist and doctor Friedrich Freese (1794-1878). It is local to the eastern aspect of southern Africa, from Kenya south to South Africa, most kinds being within Cape Provinces. Types of the previous genus Anomatheca are actually included in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia types. Some other types are also cultivated as ornamental plant life.
They are herbaceous plants which increase from a conical corm 1-2.5 cm diameter, which delivers up a tuft of slim 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 varieties have fragrant narrowly funnel-shaped flowers, although those previously located in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are used as food plants by the larvae of some Lepidoptera species 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 species and the green- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellowish, green, red and blue-mauve. They are mostly cultivated appropriately in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Because of their specific and attractive scent, they are often used in palm products, shampoos, candles, etc.[citation needed], however, the plants are mainly utilized in wedding bouquets. They could be planted in the street to redemption 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 and coil in Areas 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other species of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat somewhat than cup-shaped bouquets. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy frigid dormancy which results in development of buds inside a predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply herbal products) are crops that have no consistent woody stem above earth. Herbaceous plants may be annuals, biennials or perennials. Total annual herbaceous plants pass away completely at the end of the growing season or when they have got flowered and fruited, and they then expand again from seed. Herbaceous perennial and biennial plant life may have stems that die at the end of the growing season, but parts of the plant make it through under or close to the bottom from season to season (for biennials, before next growing season, when they blossom and perish). New growth develops from living cells left over 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 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 & most grasses. In comparison, non-herbaceous perennial crops are woody vegetation that have stems above floor that continue to be alive through the dormant season and grow shoots the next 12 months from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
