Freesia is a genus of herbaceous perennial flowering crops in the family Iridaceae, first referred to as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and known as after German botanist and doctor Friedrich Freese (1794-1878). It is native to the eastern area of southern Africa, from Kenya south to South Africa, most species being within Cape Provinces. Species of the former genus Anomatheca are now included in Freesia. The crops often called "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia kinds. Some other kinds are also cultivated as ornamental plant life.
They are really herbaceous plants which increase from a conical corm 1-2.5 cm size, which transmits 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 flowers with six tepals. Many varieties have fragrant narrowly funnel-shaped bouquets, although those previously positioned in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are being used as food crops by the larvae of some Lepidoptera varieties including Large Yellow Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" are derived from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the red- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellow, green, red and blue-mauve. They can be mostly cultivated properly in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Because of the specific and satisfying scent, they are generally used in hands lotions, shampoos, candles, etc.[citation needed], however, the flowers are mainly used in wedding bouquets. They can be planted in the semester in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature does not show up below about -7 ?C (20 ?F)), and in the spring in Zones 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other species of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat somewhat than cup-shaped blossoms. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy wintry dormancy which results in development of buds within the predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbal selections) are vegetation which have no continual woody stem above surface. Herbaceous crops may be annuals, biennials or perennials. Total annual herbaceous plants perish completely at the end of the growing season or when they have flowered and fruited, plus they then grow again from seed. Herbaceous perennial and biennial plants may have stems that die by the end of the growing season, but elements of the plant survive under or near the ground from season to season (for biennials, before next growing season, when they rose and pass away). New expansion produces from living tissue left over on or under the ground, including origins, a caudex (a thickened part of the stem at ground level) or numerous kinds 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 and most grasses. By contrast, non-herbaceous perennial vegetation are woody plant life which have stems above surface that remain alive through the dormant season and develop shoots another 12 months from the above-ground parts - these include trees, shrubs and vines.
