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 aspect of southern Africa, from Kenya south to South Africa, most species being within Cape Provinces. Kinds of the previous genus Anomatheca are now contained in Freesia. The plant life commonly known as "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of a number of Freesia species. Some other varieties are also cultivated as ornamental crops.
They are herbaceous plants which develop 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 high bearing a few leaves and a loose one-sided spike of blooms with six tepals. Many species have fragrant narrowly funnel-shaped blossoms, although those formerly located in the genus Anomatheca, such as F. laxa, have flat 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 hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the red- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellowish, green, red and blue-mauve. They can be mostly cultivated professionally in holland by about 80 growers.[3] Freesias can be commonly increased from seed. Due to their specific and attractive scent, they are generally used in palm ointments, shampoos, candles, etc.[citation needed], however, the flowers are mainly used in wedding bouquets. They could be planted in the fall in USDA Hardiness Areas 9-10 (i.e. where the temperature will not fall below about -7 ?C (20 ?F)), and in the planting season in Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other species of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat somewhat than cup-shaped flowers. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the light bulbs in proprietary solutions to satisfy frigid dormancy which results in development of buds in a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal products) are plants which have no consistent woody stem above surface. Herbaceous plants may be annuals, biennials or perennials. Total annual herbaceous plants expire completely at the end of the growing season or when they may have flowered and fruited, plus they then grow again from seed. Herbaceous perennial and biennial plant life may have stems that die at the end of the growing season, but parts of the plant make it through under or near to the bottom from season to season (for biennials, before next growing season, when they blossom and pass away). New development develops from living tissue staying on or under the ground, including origins, a caudex (a thickened portion of the stem at walk out) 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 & most grasses. In comparison, non-herbaceous perennial plant life are woody plants which have stems above surface that continue to be alive through the dormant season and expand shoots the next yr from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
