Freesia is a genus of herbaceous perennial flowering crops in the family Iridaceae, first referred to as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and named 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 kinds being within Cape Provinces. Species of the former genus Anomatheca are actually included in Freesia. The plants often called "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of lots of Freesia varieties. Some other species are also cultivated as ornamental plants.
They may be herbaceous plant life which develop from a conical corm 1-2.5 cm size, which directs up a tuft of narrow 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 bouquets with six tepals. Many types have fragrant narrowly funnel-shaped blooms, although those previously put in the genus Anomatheca, such as F. laxa, have chiseled flowers. Freesias are being used as food crops by the larvae of some Lepidoptera types including Large Yellow Underwing.
CULTIVATION AND USES
The vegetation 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 varieties and the pink- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have bouquets which range from white to yellow, red, red and blue-mauve. They are mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be easily increased from seed. Because of their specific and attractive scent, they are generally used in hands creams, shampoos, candles, etc.[citation needed], however, the bouquets are mainly used in wedding bouquets. They can be planted in the semester in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature does not show up below about -7 ?C (20 ?F)), and in the springtime in Zones 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other types of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it has flat alternatively than cup-shaped flowers. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the bulbs in proprietary methods to satisfy cool dormancy which results in development of buds within the predicted amount of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply natural remedies) are crops that have no continual woody stem above ground. Herbaceous plant life may be annuals, biennials or perennials. Total annual herbaceous plants perish completely at the end of the growing season or when they may have flowered and fruited, and they then grow again from seed. Herbaceous perennial and biennial crops may have stems that pass away at the end of the growing season, but elements of the plant survive under or near the bottom from season to season (for biennials, before next growing season, when they flower and perish). New growth develops from living tissue left over on or under the bottom, including root base, a caudex (a thickened portion of the stem at ground level) or various types of underground stems, such as lights, 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. By contrast, non-herbaceous perennial plants are woody crops that have stems above earth that continue to be alive through the dormant season and increase shoots the next time from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
