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 really is local to the eastern aspect of southern Africa, from Kenya south to South Africa, most types being within Cape Provinces. Varieties of the previous genus Anomatheca are actually contained in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped blossoms, are cultivated hybrids of lots of Freesia varieties. Some other kinds are also expanded as ornamental plants.
They may be herbaceous plant life which expand from a conical corm 1-2.5 cm size, which directs up a tuft of small 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 blooms with six tepals. Many species have fragrant narrowly funnel-shaped bouquets, although those formerly put in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food plant life by the larvae of some Lepidoptera varieties including Large Yellowish Underwing.
CULTIVATION AND USES
The vegetation usually called "freesias" are derived from crosses made in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the pink- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have flowers ranging from white to yellowish, green, red and blue-mauve. They may be mostly cultivated properly in holland by about 80 growers.[3] Freesias can be commonly increased from seed. Because of their specific and satisfying scent, they are generally used in palm products, shampoos, candles, etc.[citation needed], however, the bouquets are mainly used in wedding bouquets. They could be planted in the show up in USDA Hardiness Areas 9-10 (i.e. where in fact the temperature will not fall below about -7 ?C (20 ?F)), and in the spring and coil in Areas 4-8.
Freesia laxa (formerly called Lapeirousia laxa or Anomatheca cruenta) is one of the other species of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it includes flat somewhat than cup-shaped flowers. Extensive 'forcing' of this bulb occurs in Half Moon Bay in California where several growers chill the light bulbs in proprietary methods to satisfy cool dormancy which results in creation of buds in just a predicted amount of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plant life (in botanical use frequently simply natural remedies) are plant life which may have no prolonged woody stem above surface. Herbaceous vegetation may be annuals, biennials or perennials. Annual herbaceous plants expire completely at the end of the growing season or when they have flowered and fruited, plus they then grow again from seed. Herbaceous perennial and biennial crops may have stems that die at the end of the growing season, but elements of the plant make it through under or near the ground from season to season (for biennials, before next growing season, when they blossom and pass away). New expansion grows from living tissues staying on or under the bottom, including root base, a caudex (a thickened part of the stem at ground level) or various types 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 plants are woody crops that have stems above floor that continue to be alive through the dormant season and increase shoots the next calendar year from the above-ground parts - included in these are trees, shrubs and vines.
