Freesia is a genus of herbaceous perennial flowering crops 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 really is indigenous to the eastern area of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Types of the past genus Anomatheca are now contained in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of lots of Freesia types. Some other species are also harvested as ornamental plants.
These are herbaceous plants which develop from a conical corm 1-2.5 cm size, 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 formerly placed in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera kinds including Large Yellow Underwing.
CULTIVATION AND USES
The vegetation 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 types and the pink- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have blossoms ranging from white to yellow, pink, red and blue-mauve. They are really mostly cultivated expertly in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Because of the specific and satisfying scent, they are often used in hands products, shampoos, candles, etc.[citation needed], however, the blooms are mainly utilized in wedding bouquets. They could be planted in the show up in USDA Hardiness Areas 9-10 (i.e. where the temperature does not fall season below about -7 ?C (20 ?F)), and in the planting season 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 somewhat than cup-shaped blossoms. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy wintry dormancy which results in development of buds inside a predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply natural herbs) are crops which have no continual woody stem above ground. Herbaceous plant life may be annuals, biennials or perennials. Annual herbaceous plants perish completely at the end of the growing season or when they have got flowered and fruited, plus they then develop 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 make it through under or close to the ground from season to season (for biennials, until the next growing season, when they blossom and expire). New progress develops 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 lights, corms, stolons, rhizomes and tubers. Types of herbaceous biennials include carrot, parsnip and common ragwort; herbaceous perennials include potato, peony, hosta, mint, most ferns and most grasses. By contrast, non-herbaceous perennial plants are woody plants that have stems above floor that remain alive during the dormant season and develop shoots another 12 months from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
