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 side of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Types of the ex - genus Anomatheca are now included in Freesia. The crops commonly known as "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of lots of Freesia varieties. Some other species are also grown up as ornamental crops.
They are simply herbaceous plant life which develop from a conical corm 1-2.5 cm diameter, which delivers up a tuft of small leaves 10-30 cm long, and a sparsely branched stem 10-40 cm extra tall bearing a few leaves and a loose one-sided spike of blossoms with six tepals. Many types have fragrant narrowly funnel-shaped bouquets, although those previously located in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera species including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" derive from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the red- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have flowers ranging from white to yellow, red, red and blue-mauve. They are mostly cultivated expertly in the Netherlands by about 80 growers.[3] Freesias can be quickly increased from seed. Because of the specific and pleasing scent, they are generally used in side products, shampoos, candles, etc.[citation needed], however, the flowers are mainly used 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 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 commonly cultivated. Smaller than the scented freesia cultivars, they have 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 solutions to satisfy cold dormancy which results in formation of buds inside a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbs) are plant life which have no continual woody stem above floor. Herbaceous vegetation may be annuals, biennials or perennials. 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 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 bloom and pass away). New expansion produces from living tissue left over on or under the ground, including roots, 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. Examples of herbaceous biennials include carrot, parsnip and common ragwort; herbaceous perennials include potato, peony, hosta, mint, most ferns and most grasses. In comparison, non-herbaceous perennial plant life are woody crops which have stems above earth that continue to be alive through the dormant season and develop shoots another calendar year from the above-ground parts - these include trees, shrubs and vines.
