Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first referred to as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and known as after German botanist and doctor Friedrich Freese (1794-1878). It really is native to the eastern side of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Species of the previous genus Anomatheca are actually included in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of Freesia kinds. Some other kinds are also harvested as ornamental crops.
They are herbaceous plants 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 types have fragrant narrowly funnel-shaped blooms, although those formerly positioned in the genus Anomatheca, such as F. laxa, have level flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera kinds including Large Yellow 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 varieties and the red- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellowish, green, red and blue-mauve. They are really mostly cultivated professionally in the Netherlands by about 80 growers.[3] Freesias can be quickly increased from seed. Because of their specific and desirable scent, they are generally used in hands creams, shampoos, candles, etc.[citation needed], however, the bouquets are mainly used in wedding bouquets. They can be planted in the land in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature does not fall below about -7 ?C (20 ?F)), and in the spring in Zones 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other types of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it includes flat somewhat than cup-shaped blossoms. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy frigid dormancy which results in creation of buds within the predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbal products) are plants which have no consistent woody stem above ground. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants pass away completely at the end of the growing season or when they may have flowered and fruited, and they then increase again from seed. Herbaceous perennial and biennial plant life may have stems that die by the end of the growing season, but elements of the plant survive under or close to the ground from season to season (for biennials, before next growing season, when they bloom and expire). New progress develops from living tissue staying on or under the ground, including root base, a caudex (a thickened portion 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. By contrast, non-herbaceous perennial vegetation are woody vegetation which have stems above earth that continue to be alive during the dormant season and develop shoots another yr from the above-ground parts - included in these are trees, shrubs and vines.
