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 really is native to the eastern aspect of southern Africa, from Kenya south to South Africa, most varieties being found in Cape Provinces. Kinds of the former genus Anomatheca are now included in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of a number of Freesia kinds. Some other kinds are also produced as ornamental vegetation.
They are simply herbaceous plants which increase from a conical corm 1-2.5 cm size, which transmits up a tuft of thin 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 bouquets with six tepals. Many species have fragrant narrowly funnel-shaped bouquets, although those formerly put in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food plants by the larvae of some Lepidoptera types including Large Yellow Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" are derived from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the green- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellowish, green, red and blue-mauve. These are mostly cultivated properly in the Netherlands by about 80 growers.[3] Freesias can be readily increased from seed. Due to their specific and pleasing scent, they are generally used in side ointments, shampoos, candles, etc.[citation needed], however, the blossoms are mainly utilized in wedding bouquets. They could be planted in the show up in USDA Hardiness Areas 9-10 (i.e. where 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, it offers flat alternatively than cup-shaped bouquets. 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 a predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply herbal selections) are plant life that contain no prolonged woody stem above earth. Herbaceous vegetation 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, and they then develop again from seed. Herbaceous perennial and biennial vegetation may have stems that die by the end of the growing season, but elements of the plant endure under or near to the bottom from season to season (for biennials, before next growing season, when they bloom and perish). New development grows from living tissue staying on or under the ground, including origins, a caudex (a thickened portion of the stem at walk out) or various types of underground stems, such as light 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. By contrast, non-herbaceous perennial plant life are woody crops which have stems above ground that stay alive through the dormant season and develop shoots another yr from the above-ground parts - these include trees, shrubs and vines.
