Freesia is a genus of herbaceous perennial flowering plant life in the family Iridaceae, first described as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and called after German botanist and doctor Friedrich Freese (1794-1878). It really is indigenous to the eastern aspect of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Kinds of the former genus Anomatheca are actually contained in Freesia. The crops often called "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia kinds. Some other varieties are also cultivated as ornamental plants.
They may be herbaceous crops which grow from a conical corm 1-2.5 cm size, which delivers 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 blossoms with six tepals. Many varieties have fragrant narrowly funnel-shaped flowers, although those previously positioned in the genus Anomatheca, such as F. laxa, have toned flowers. Freesias are being used as food plant life by the larvae of some Lepidoptera kinds including Large Yellowish 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 green- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blooms which range from white to yellowish, red, red and blue-mauve. They can be mostly cultivated professionally in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Because of the specific and satisfying scent, they are often used in hand creams, shampoos, candles, etc.[citation needed], however, the blooms are mainly used in wedding bouquets. They can be planted in the fall in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature does not fall below about -7 ?C (20 ?F)), and in the planting season in Areas 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other kinds of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it has flat rather than cup-shaped plants. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy cool dormancy which results in formation of buds within the predicted quantity of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbal remedies) are plants that have no prolonged woody stem above floor. Herbaceous crops 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 crops may have stems that pass away by the end of the growing season, but elements of the plant survive under or near to the ground from season to season (for biennials, until the next growing season, when they bloom and expire). New growth grows from living tissue staying on or under the ground, including roots, a caudex (a thickened part of the stem at ground level) or numerous kinds 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 vegetation are woody crops that have stems above floor that stay alive through the dormant season and grow shoots the next calendar year from the above-ground parts - these include trees, shrubs and vines.
