Freesia is a genus of herbaceous perennial flowering plants 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 is local to the eastern part of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Types of the former genus Anomatheca are actually contained in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of a number of Freesia kinds. Some other kinds are also grown up as ornamental plant life.
They can be herbaceous vegetation which increase from a conical corm 1-2.5 cm size, which directs up a tuft of slim 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 blossoms with six tepals. Many types have fragrant narrowly funnel-shaped blossoms, although those formerly located in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are used as food crops by the larvae of some Lepidoptera varieties including Large Yellowish Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" derive from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the green- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellow, green, red and blue-mauve. They are mostly cultivated expertly in holland by about 80 growers.[3] Freesias can be immediately increased from seed. Due to their specific and pleasing scent, they are often used in hands ointments, shampoos, candles, etc.[citation needed], however, the plants are mainly utilized in wedding bouquets. They could be planted in the show up in USDA Hardiness Areas 9-10 (i.e. where the temperature does not show up below about -7 ?C (20 ?F)), and in the planting season in Areas 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 offers flat rather than cup-shaped blooms. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the light bulbs in proprietary methods to satisfy frigid dormancy which results in creation of buds in just a predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbal products) are crops that contain no consistent woody stem above earth. Herbaceous vegetation may be annuals, biennials or perennials. Total annual herbaceous plants pass away completely by the end of the growing season or when they have got flowered and fruited, plus they then grow 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 endure under or near the bottom from season to season (for biennials, until the next growing season, when they flower and perish). New growth produces from living tissue staying on or under the ground, including root base, a caudex (a thickened portion of the stem at walk out) or various types of underground stems, such as light 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. In comparison, non-herbaceous perennial plants are woody plants that have stems above ground that continue to be alive through the dormant season and increase shoots the next yr from the above-ground parts - these include trees, shrubs and vines.
