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 named after German botanist and doctor Friedrich Freese (1794-1878). It is native to the eastern side of southern Africa, from Kenya south to South Africa, most varieties being within Cape Provinces. Kinds of the past genus Anomatheca are actually included in Freesia. The vegetation commonly known as "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of lots of Freesia kinds. Some other varieties are also expanded as ornamental vegetation.
These are herbaceous plants which expand from a conical corm 1-2.5 cm size, which transmits 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 blossoms with six tepals. Many kinds have fragrant narrowly funnel-shaped bouquets, although those previously located in the genus Anomatheca, such as F. laxa, have smooth flowers. Freesias are used as food crops by the larvae of some Lepidoptera species including Large Yellow Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" derive from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these species and the pink- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellow, green, red and blue-mauve. They are mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be quickly increased from seed. Due to their specific and satisfying scent, they are generally used in side ointments, shampoos, candles, etc.[citation needed], however, the bouquets are mainly utilized in wedding bouquets. They could be planted in the land in USDA Hardiness Areas 9-10 (i.e. where the temperature does not fall below about -7 ?C (20 ?F)), and in the springtime in Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other kinds of the genus which is often cultivated. Smaller than the scented freesia cultivars, it offers 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 cool dormancy which results in formation of buds within a predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbal selections) are plant life which have no continual woody stem above surface. Herbaceous vegetation may be annuals, biennials or perennials. Annual herbaceous plants die completely by the end of the growing season or when they have flowered and fruited, plus they then increase again from seed. Herbaceous perennial and biennial plant life may have stems that pass away at the end of the growing season, but parts of the plant survive under or near the ground from season to season (for biennials, before next growing season, when they blossom and perish). New growth builds up from living cells staying on or under the bottom, including origins, a caudex (a thickened part 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 and most grasses. By contrast, non-herbaceous perennial plants are woody vegetation that have stems above surface that stay alive during the dormant season and grow shoots another calendar year from the above-ground parts - included in these are trees, shrubs and vines.
