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 known as 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 types being found in Cape Provinces. Kinds 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 varieties. Some other kinds are also cultivated as ornamental vegetation.
They are really herbaceous crops which increase 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 large bearing a few leaves and a loose one-sided spike of blossoms with six tepals. Many types have fragrant narrowly funnel-shaped blossoms, although those formerly placed in the genus Anomatheca, such as F. laxa, have toned flowers. Freesias are being used as food plants by the larvae of some Lepidoptera types including Large Yellow 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 species and the pink- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blossoms ranging from white to yellow, green, red and blue-mauve. They are simply mostly cultivated professionally in holland by about 80 growers.[3] Freesias can be quickly increased from seed. Because of their specific and desirable scent, they are often used in hands lotions, shampoos, candles, etc.[citation needed], however, the blooms are mainly used in wedding bouquets. They could be planted in the fall season in USDA Hardiness Zones 9-10 (i.e. where the temperature will not fall 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 includes flat somewhat than cup-shaped bouquets. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy wintry dormancy which results in formation of buds in a predicted quantity of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal remedies) are plants which may have no continual woody stem above ground. Herbaceous vegetation may be annuals, biennials or perennials. Annual herbaceous plants expire completely at 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 ground from season to season (for biennials, until the next growing season, when they rose and perish). New progress builds up from living tissue remaining on or under the ground, 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. Types 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 plant life are woody plants that have stems above floor that remain alive during the dormant season and grow shoots another 12 months from the above-ground parts - included in these are trees, shrubs and vines.
