Freesia is a genus of herbaceous perennial flowering plants in the family Iridaceae, first referred to as a genus in 1866 by Chr. Fr. Echlon (1795-1868) and called after German botanist and doctor Friedrich Freese (1794-1878). It really is native to the eastern side of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Types of the past genus Anomatheca are actually included in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of lots of Freesia types. Some other types are also produced as ornamental vegetation.
These are herbaceous crops which grow 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 extra tall bearing a few leaves and a loose one-sided spike of blossoms with six tepals. Many types have fragrant narrowly funnel-shaped blooms, although those formerly positioned in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are being used as food vegetation by the larvae of some Lepidoptera varieties including Large Yellowish Underwing.
CULTIVATION AND USES
The plants usually called "freesias" are derived from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these varieties and the red- and yellow-flowered kinds of F. corymbosa. Modern tetraploid cultivars have blossoms ranging from white to yellowish, green, red and blue-mauve. They can be mostly cultivated properly in holland by about 80 growers.[3] Freesias can be quickly increased from seed. Due to their specific and desirable scent, they are often used in hands lotions, shampoos, candles, etc.[citation needed], however, the flowers are mainly utilized in wedding bouquets. They can be planted in the fall in USDA Hardiness Zones 9-10 (i.e. where the temperature does not fall season below about -7 ?C (20 ?F)), and in the planting season 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, they have flat somewhat than cup-shaped blooms. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary methods to satisfy cool dormancy which results in creation of buds within the predicted quantity of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply natural herbs) are crops which may have no prolonged woody stem above surface. Herbaceous plant life may be annuals, biennials or perennials. Annual herbaceous plants pass away completely at the end of the growing season or when they have flowered and fruited, and they then expand again from seed. Herbaceous perennial and biennial plants may have stems that pass away 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 bloom and pass away). New expansion develops from living tissues left over on or under the bottom, including roots, a caudex (a thickened portion of the stem at ground level) or various types of underground stems, such as bulbs, corms, stolons, rhizomes and tubers. Examples of herbaceous biennials include carrot, parsnip and common ragwort; herbaceous perennials include potato, peony, hosta, mint, most ferns and most grasses. In comparison, non-herbaceous perennial plants are woody plant life which have stems above ground that remain alive through the dormant season and develop shoots another season from the above-ground parts - these include trees and shrubs, shrubs and vines.
