Freesia is a genus of herbaceous perennial flowering vegetation in the family Iridaceae, first described 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 local to the eastern side of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Types of the previous genus Anomatheca are actually contained in Freesia. The vegetation commonly known as "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of lots of Freesia kinds. Some other kinds are also produced as ornamental plants.
These are herbaceous vegetation which grow from a conical corm 1-2.5 cm diameter, which transmits up a tuft of narrow 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 plants, although those previously put in the genus Anomatheca, such as F. laxa, have level flowers. Freesias are being used as food plant life by the larvae of some Lepidoptera species including Large Yellowish Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" derive from crosses made in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these varieties and the red- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have plants ranging from white to yellowish, green, red and blue-mauve. These are mostly cultivated skillfully 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 palm creams, shampoos, candles, etc.[citation needed], however, the blossoms are mainly used in wedding bouquets. They could be planted in the street to redemption in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature does not show up below about -7 ?C (20 ?F)), and in the spring in Zones 4-8.
Freesia laxa (formerly 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, it has flat rather than cup-shaped blossoms. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy cold dormancy which results in creation of buds inside a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply herbs) are plants which may have no continual woody stem above floor. Herbaceous plant life may be annuals, biennials or perennials. Total annual herbaceous plants expire completely at the end of the growing season or when they have got flowered and fruited, and they then expand again from seed. Herbaceous perennial and biennial plant life may have stems that die by the end of the growing season, but parts of the plant endure under or near the ground from season to season (for biennials, before next growing season, when they blossom and pass away). New development builds up from living tissues remaining on or under the ground, including origins, a caudex (a thickened part 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. By contrast, non-herbaceous perennial plants are woody plant life which have stems above floor that remain alive through the dormant season and increase shoots another calendar year from the above-ground parts - included in these are trees, shrubs and vines.
