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 really is local to the eastern side of southern Africa, from Kenya south to South Africa, most species being within Cape Provinces. Types of the previous genus Anomatheca are actually contained in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of a number of Freesia types. Some other kinds are also harvested as ornamental plant life.
They are really herbaceous vegetation which increase from a conical corm 1-2.5 cm size, which directs up a tuft of small leaves 10-30 cm long, and a sparsely branched stem 10-40 cm large bearing a few leaves and a loose one-sided spike of plants with six tepals. Many types have fragrant narrowly funnel-shaped bouquets, although those previously located in the genus Anomatheca, such as F. laxa, have toned flowers. Freesias are being used as food plant life by the larvae of some Lepidoptera kinds including Large Yellow Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" derive from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the green- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellow, green, red and blue-mauve. They are mostly cultivated properly in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Due to their specific and desirable scent, they are often used in hands products, shampoos, candles, etc.[citation needed], however, the blossoms are mainly used in wedding bouquets. They can be planted in the show up in USDA Hardiness Zones 9-10 (i.e. where the temperature will not show up below about -7 ?C (20 ?F)), and in the springtime 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 plants. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy chilly dormancy which results in formation of buds in just a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply herbal products) are crops which have no consistent woody stem above ground. Herbaceous plants may be annuals, biennials or perennials. Annual herbaceous plants expire completely by the end of the growing season or when they have flowered and fruited, plus they then grow again from seed. Herbaceous perennial and biennial vegetation may have stems that die at the end of the growing season, but parts of the plant make it through under or close to the bottom from season to season (for biennials, until the next growing season, when they blossom and pass away). New progress develops from living tissues staying on or under the bottom, including roots, a caudex (a thickened part of the stem at walk out) or various types 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 earth that continue to be alive through the dormant season and expand shoots another yr from the above-ground parts - included in these are trees, shrubs and vines.
