Freesia is a genus of herbaceous perennial flowering crops 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 really is indigenous to the eastern area of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Kinds of the former genus Anomatheca are actually included in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of lots of Freesia species. Some other kinds are also harvested as ornamental crops.
They may be herbaceous vegetation which increase from a conical corm 1-2.5 cm diameter, which directs 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 blossoms with six tepals. Many varieties have fragrant narrowly funnel-shaped plants, although those previously positioned in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food plant life by the larvae of some Lepidoptera species including Large Yellowish Underwing.
CULTIVATION AND USES
The vegetation 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 kinds and the green- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have blossoms which range from white to yellowish, green, red and blue-mauve. They are simply mostly cultivated appropriately in the Netherlands by about 80 growers.[3] Freesias can be easily increased from seed. Because of the specific and pleasing scent, they are often used in hand creams, shampoos, candles, etc.[citation needed], however, the bouquets are mainly used in wedding bouquets. They can be planted in the land in USDA Hardiness Zones 9-10 (i.e. where 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 varieties of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it offers flat rather than cup-shaped bouquets. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy frigid dormancy which results in creation of buds in just a predicted quantity of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply natural remedies) are plants which may have no prolonged woody stem above earth. Herbaceous plants may be annuals, biennials or perennials. Total annual herbaceous plants die completely by the end of the growing season or when they may have 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 endure under or close to the ground from season to season (for biennials, until the next growing season, when they rose and expire). New development grows from living tissues staying on or under the ground, including root base, a caudex (a thickened portion of the stem at walk out) or various types of underground stems, such as lights, 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 crops are woody plants that have stems above ground that continue to be alive through the dormant season and develop shoots the next yr from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
