Freesia is a genus of herbaceous perennial flowering plant life in the family Iridaceae, first referred to 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 local to the eastern side of southern Africa, from Kenya south to South Africa, most kinds being within Cape Provinces. Types of the previous genus Anomatheca are actually included in Freesia. The plant life often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of a number of Freesia kinds. Some other varieties are also grown up as ornamental plant life.
They are simply herbaceous crops which expand from a conical corm 1-2.5 cm size, which transmits up a tuft of slim 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 types 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 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 kinds and the pink- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellow, green, red and blue-mauve. They are really mostly cultivated professionally in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Because of their specific and satisfying scent, they are often used in hands products, shampoos, candles, etc.[citation needed], however, the bouquets are mainly utilized in wedding bouquets. They can be planted in the fall season in USDA Hardiness Areas 9-10 (i.e. where the temperature will not land below about -7 ?C (20 ?F)), and in the planting season in Areas 4-8.
Freesia laxa (previously 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, they have flat rather than cup-shaped plants. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy frosty dormancy which results in creation of buds within a predicted volume of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbs) are plant life which have no persistent woody stem above floor. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants expire completely by the end of the growing season or when they have got flowered and fruited, plus they then develop again from seed. Herbaceous perennial and biennial crops may have stems that die by the end of the growing season, but parts of the plant survive under or near the bottom from season to season (for biennials, until the next growing season, when they rose and die). New development builds up from living tissue staying on or under the bottom, including roots, 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. 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 vegetation that have stems above floor that remain alive during the dormant season and grow shoots another time from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
