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 called 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 species being within Cape Provinces. Types of the former genus Anomatheca are actually included in Freesia. The plant life often called "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of lots of Freesia types. Some other varieties are also produced as ornamental plant life.
They can be herbaceous vegetation which increase from a conical corm 1-2.5 cm size, which transmits 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 blossoms with six tepals. Many kinds have fragrant narrowly funnel-shaped plants, although those previously located in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are used as food vegetation 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 varieties and the red- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have plants ranging from white to yellow, red, red and blue-mauve. They are really mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Because of their specific and desirable scent, they are generally used in hand creams, shampoos, candles, etc.[citation needed], however, the blossoms are mainly utilized 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 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 species of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it includes flat alternatively than cup-shaped flowers. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy chilly dormancy which results in formation of buds inside a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply herbal products) are vegetation that contain no persistent woody stem above surface. Herbaceous plants 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 grow again from seed. Herbaceous perennial and biennial crops may have stems that pass away by the end of the growing season, but elements of the plant endure under or near the ground from season to season (for biennials, until the next growing season, when they blossom and perish). New development produces from living tissues left over 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. 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 plants are woody vegetation which have stems above floor that continue to be alive during the dormant season and develop shoots another season from the above-ground parts - these include trees, shrubs and vines.
