Freesia is a genus of herbaceous perennial flowering vegetation 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 native to the eastern aspect of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Varieties of the previous genus Anomatheca are actually contained in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of lots of Freesia kinds. Some other types are also grown up as ornamental plants.
They are really herbaceous plants which develop from a conical corm 1-2.5 cm size, which delivers up a tuft of thin leaves 10-30 cm long, and a sparsely branched stem 10-40 cm tall bearing a few leaves and a loose one-sided spike of plants with six tepals. Many kinds have fragrant narrowly funnel-shaped bouquets, although those formerly positioned in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are used as food plant life by the larvae of some Lepidoptera varieties including Large Yellow Underwing.
CULTIVATION AND USES
The plant life 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 varieties and the red- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have flowers ranging from white to yellow, red, red and blue-mauve. They can be mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be immediately increased from seed. Because of the specific and attractive scent, they are often used in hands products, shampoos, candles, etc.[citation needed], however, the plants are mainly used in wedding bouquets. They could be planted in the fall in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature will not fall below about -7 ?C (20 ?F)), and in the spring in Areas 4-8.
Freesia laxa (previously 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 rather than cup-shaped flowers. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary methods to satisfy frigid dormancy which results in creation of buds in a predicted amount of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbal selections) are plants that contain no consistent woody stem above surface. Herbaceous plants may be annuals, biennials or perennials. Total annual herbaceous plants pass away completely at the end of the growing season or when they have flowered and fruited, plus they then develop again from seed. Herbaceous perennial and biennial plants may have stems that pass away by the end of the growing season, but parts of the plant endure under or near the bottom from season to season (for biennials, before next growing season, when they rose and pass away). New development grows from living tissue staying on or under the ground, including root base, a caudex (a thickened part of the stem at ground level) or numerous kinds of underground stems, such as 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 and most grasses. In comparison, non-herbaceous perennial crops are woody plants that have stems above surface that continue to be alive through the dormant season and increase shoots another calendar year from the above-ground parts - included in these are trees, shrubs and vines.
