Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first referred to as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and called after German botanist and doctor Friedrich Freese (1794-1878). It is local to the eastern area of southern Africa, from Kenya south to South Africa, most kinds being within Cape Provinces. Varieties of the former genus Anomatheca are actually included in Freesia. The crops often called "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of a number of Freesia kinds. Some other varieties are also produced as ornamental crops.
These are herbaceous crops which grow 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 tall bearing a few leaves and a loose one-sided spike of plants with six tepals. Many types have fragrant narrowly funnel-shaped flowers, although those formerly positioned in the genus Anomatheca, such as F. laxa, have level flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera species including Large Yellowish Underwing.
CULTIVATION AND USES
The crops 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 pink- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellowish, pink, red and blue-mauve. They can be mostly cultivated expertly in the Netherlands by about 80 growers.[3] Freesias can be conveniently increased from seed. Due to their specific and attractive scent, they are often used in palm ointments, shampoos, candles, etc.[citation needed], however, the plants are mainly utilized in wedding bouquets. They could be planted in the street to redemption in USDA Hardiness Zones 9-10 (i.e. where the temperature does not land below about -7 ?C (20 ?F)), and in the springtime in Zones 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other kinds of the genus which is often cultivated. Smaller than the scented freesia cultivars, it offers flat alternatively than cup-shaped flowers. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary solutions to satisfy cold dormancy which results in creation of buds within the predicted quantity of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal products) are vegetation which have no prolonged woody stem above ground. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants die 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 vegetation may have stems that die at the end of the growing season, but elements of the plant make it through under or near to the ground from season to season (for biennials, until the next growing season, when they flower and pass away). New development develops from living tissues left over on or under the bottom, including roots, a caudex (a thickened part of the stem at ground level) or various types of underground stems, such as lights, 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 vegetation are woody plants which have stems above ground that remain alive during the dormant season and grow shoots the next time from the above-ground parts - these include trees, shrubs and vines.
