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 really is native to the eastern area of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Types of the previous genus Anomatheca are actually included in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of a number of Freesia types. Some other kinds are also produced as ornamental vegetation.
They can be herbaceous crops which increase from a conical corm 1-2.5 cm size, which sends 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 kinds have fragrant narrowly funnel-shaped plants, although those previously positioned in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are used as food crops by the larvae of some Lepidoptera species including Large Yellow Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" are derived from crosses manufactured in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the pink- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellowish, green, red and blue-mauve. They can be mostly cultivated professionally in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Because of their specific and pleasing scent, they are generally used in hands products, shampoos, candles, etc.[citation needed], however, the flowers are mainly used in wedding bouquets. They can be planted in the fall season 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 Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other kinds of the genus which is often cultivated. Smaller than the scented freesia cultivars, it has flat somewhat than cup-shaped flowers. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy cold dormancy which results in creation of buds in a predicted amount of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal selections) are crops which may have no continual woody stem above earth. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants pass away completely by the end of the growing season or when they have got flowered and fruited, plus they then expand again from seed. Herbaceous perennial and biennial plant life may have stems that pass away by the end of the growing season, but elements of the plant endure under or near the bottom from season to season (for biennials, before next growing season, when they blossom and perish). New expansion grows from living tissues remaining on or under the bottom, including roots, a caudex (a thickened portion of the stem at ground level) or various types of underground stems, such as bulbs, corms, stolons, rhizomes and tubers. Types 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 plant life are woody crops that have stems above surface that continue to be alive through the dormant season and develop shoots the next year from the above-ground parts - these include trees, shrubs and vines.
