Freesia is a genus of herbaceous perennial flowering plant life 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 native to the eastern area of southern Africa, from Kenya south to South Africa, most varieties being within Cape Provinces. Kinds of the former genus Anomatheca are now contained in Freesia. The plants commonly known as "freesias", with fragrant funnel-shaped blooms, are cultivated hybrids of a number of Freesia species. Some other species are also cultivated as ornamental vegetation.
They can be herbaceous vegetation which develop from a conical corm 1-2.5 cm diameter, which directs up a tuft of thin 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 plants with six tepals. Many varieties have fragrant narrowly funnel-shaped plants, although those previously positioned in the genus Anomatheca, such as F. laxa, have flat flowers. Freesias are used as food vegetation by the larvae of some Lepidoptera kinds including Large Yellowish Underwing.
CULTIVATION AND USES
The plants usually called "freesias" are derived 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 kinds of F. corymbosa. Modern tetraploid cultivars have blooms ranging from white to yellowish, pink, red and blue-mauve. They can be mostly cultivated appropriately in the Netherlands by about 80 growers.[3] Freesias can be easily increased from seed. Because of the specific and pleasing scent, they are generally used in palm ointments, shampoos, candles, etc.[citation needed], however, the bouquets are mainly used in wedding bouquets. They could be planted in the semester in USDA Hardiness Areas 9-10 (i.e. where the temperature will 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 types of the genus which is often cultivated. Smaller than the scented freesia cultivars, it includes flat rather than cup-shaped blossoms. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary methods to satisfy frosty dormancy which results in development of buds in just a predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbs) are plant life which have no prolonged woody stem above ground. Herbaceous plants may be annuals, biennials or perennials. Total annual herbaceous plants perish completely by the end of the growing season or when they have got flowered and fruited, plus they then grow again from seed. Herbaceous perennial and biennial vegetation may have stems that pass away at the end of the growing season, but parts of the plant endure under or near to the bottom from season to season (for biennials, until the next growing season, when they flower and die). New growth builds up from living tissues left over on or under the ground, including root base, 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 & most grasses. By contrast, non-herbaceous perennial plant life are woody crops which have stems above floor that remain alive through the dormant season and increase shoots the next year from the above-ground parts - included in these are trees, shrubs and vines.
