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 named after German botanist and doctor Friedrich Freese (1794-1878). It is indigenous to the eastern side of southern Africa, from Kenya south to South Africa, most varieties being found in Cape Provinces. Varieties of the former genus Anomatheca are now contained in Freesia. The plants often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of lots of Freesia kinds. Some other species are also produced as ornamental plants.
They are herbaceous vegetation which develop from a conical corm 1-2.5 cm diameter, which transmits up a tuft of small 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 plants with six tepals. Many varieties have fragrant narrowly funnel-shaped bouquets, although those formerly 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 Yellowish Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" are derived from crosses made in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the pink- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blossoms which range from white to yellow, red, red and blue-mauve. They may be mostly cultivated skillfully in the Netherlands by about 80 growers.[3] Freesias can be easily increased from seed. Because of the specific and satisfying scent, they are often used in side lotions, shampoos, candles, etc.[citation needed], however, the blooms are mainly utilized in wedding bouquets. They can be planted in the fall in USDA Hardiness Zones 9-10 (i.e. where the temperature does not show up below about -7 ?C (20 ?F)), and in the spring in Areas 4-8.
Freesia laxa (formerly 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 offers flat somewhat than cup-shaped blooms. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the light bulbs in proprietary solutions to satisfy cold 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 products) are vegetation that have no persistent woody stem above earth. Herbaceous vegetation may be annuals, biennials or perennials. Total annual herbaceous plants die completely by the end of the growing season or when they have flowered and fruited, plus they then increase again from seed. Herbaceous perennial and biennial vegetation may have stems that die at the end of the growing season, but parts of the plant make it through under or near the bottom from season to season (for biennials, before next growing season, when they bloom and expire). New growth produces from living tissues staying on or under the bottom, including origins, a caudex (a thickened portion of the stem at walk out) or various types of underground stems, such as 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 & most grasses. By contrast, non-herbaceous perennial crops are woody vegetation that have stems above ground that continue to be alive during the dormant season and grow shoots another 12 months from the above-ground parts - these include trees, shrubs and vines.
