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 named after German botanist and doctor Friedrich Freese (1794-1878). It is native to the eastern part of southern Africa, from Kenya south to South Africa, most kinds being within Cape Provinces. Varieties of the past genus Anomatheca are now included in Freesia. The crops often called "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of lots of Freesia varieties. Some other types are also expanded as ornamental plants.
They can be herbaceous plants which increase from a conical corm 1-2.5 cm diameter, which transmits up a tuft of small 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 species have fragrant narrowly funnel-shaped bouquets, although those previously located in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are being used as food plant life by the larvae of some Lepidoptera types including Large Yellowish Underwing.
CULTIVATION AND USES
The crops usually called "freesias" derive from crosses made 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 forms of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellowish, pink, red and blue-mauve. These are mostly cultivated skillfully 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 side lotions, shampoos, candles, etc.[citation needed], however, the blooms are mainly utilized in wedding bouquets. They can be planted in the street to redemption in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature does not fall season below about -7 ?C (20 ?F)), and in the spring and coil in Areas 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 alternatively than cup-shaped plants. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the bulbs in proprietary solutions to satisfy frigid dormancy which results in creation of buds within a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal remedies) are crops that have no continual woody stem above floor. Herbaceous plants may be annuals, biennials or perennials. Annual herbaceous plants die completely by the end of the growing season or when they have got flowered and fruited, and they then develop again from seed. Herbaceous perennial and biennial plant life may have stems that pass away at the end of the growing season, but parts of the plant make it through under or near to the bottom from season to season (for biennials, before next growing season, when they flower and expire). New development produces from living tissue staying on or under the ground, including roots, a caudex (a thickened portion 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 & most grasses. In comparison, non-herbaceous perennial crops are woody crops that have stems above floor that stay alive through the dormant season and increase shoots the next time from the above-ground parts - included in these are trees, shrubs and vines.
