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 named after German botanist and doctor Friedrich Freese (1794-1878). It really is native to the eastern part of southern Africa, from Kenya south to South Africa, most kinds being within Cape Provinces. Kinds of the ex - genus Anomatheca are actually contained in Freesia. The plants often called "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of a number of Freesia types. Some other varieties are also cultivated as ornamental plant life.
They are herbaceous vegetation which expand from a conical corm 1-2.5 cm diameter, which delivers up a tuft of narrow 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 bouquets with six tepals. Many kinds have fragrant narrowly funnel-shaped plants, although those previously placed in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food vegetation by the larvae of some Lepidoptera types including Large Yellow Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" derive from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these species and the pink- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have plants ranging from white to yellowish, green, red and blue-mauve. They may be mostly cultivated appropriately in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Because of their specific and satisfying scent, they are generally used in hand products, shampoos, candles, etc.[citation needed], however, the plants are mainly utilized in wedding bouquets. They could be planted in the semester in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature will not fall season below about -7 ?C (20 ?F)), and in the springtime in Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other species of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it has flat rather than cup-shaped blooms. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the light bulbs in proprietary methods to satisfy cool dormancy which results in development of buds inside a predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal selections) are plant life that contain no prolonged woody stem above floor. Herbaceous vegetation may be annuals, biennials or perennials. 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 plants may have stems that die at the end of the growing season, but elements of the plant endure under or near to the bottom from season to season (for biennials, until the next growing season, when they flower and perish). New development advances from living cells left over 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 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 and most grasses. By contrast, non-herbaceous perennial plant life are woody crops that have stems above earth that stay alive through the dormant season and increase shoots the next time from the above-ground parts - these include trees and shrubs, shrubs and vines.
