Freesia is a genus of herbaceous perennial flowering crops 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 types being found in Cape Provinces. Varieties of the ex - genus Anomatheca are actually contained in Freesia. The plants often called "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of lots of Freesia species. Some other types are also grown as ornamental vegetation.
They may be herbaceous plant life which increase from a conical corm 1-2.5 cm size, which transmits up a tuft of slim 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 bouquets with six tepals. Many types have fragrant narrowly funnel-shaped plants, although those previously placed in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food plant life by the larvae of some Lepidoptera types including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" derive from crosses manufactured in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the green- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have plants ranging from white to yellowish, green, red and blue-mauve. They may be mostly cultivated professionally in holland by about 80 growers.[3] Freesias can be commonly increased from seed. Because of their specific and desirable scent, they are often used in hand creams, shampoos, candles, etc.[citation needed], however, the plants are mainly utilized in wedding bouquets. They can be planted in the semester in USDA Hardiness Areas 9-10 (i.e. where the temperature will not land 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 varieties of the genus which is often cultivated. Smaller than the scented freesia cultivars, they have flat rather than cup-shaped bouquets. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary solutions to satisfy chilly dormancy which results in development of buds inside a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbal selections) are plant life that have no persistent woody stem above ground. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants expire completely at the end of the growing season or when they may have flowered and fruited, and they then develop again from seed. Herbaceous perennial and biennial plants may have stems that die at the end of the growing season, but elements of the plant endure under or near the ground from season to season (for biennials, until the next growing season, when they flower and pass away). New development produces from living cells staying on or under the bottom, including origins, a caudex (a thickened portion of the stem at walk out) or numerous kinds of underground stems, such as light 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 & most grasses. In comparison, non-herbaceous perennial vegetation are woody vegetation which have stems above floor that continue to be alive through the dormant season and develop shoots another yr from the above-ground parts - included in these are trees, shrubs and vines.
