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 named after German botanist and doctor Friedrich Freese (1794-1878). It really is indigenous to the eastern part of southern Africa, from Kenya south to South Africa, most varieties being found in Cape Provinces. Kinds of the former genus Anomatheca are now included in Freesia. The crops commonly known as "freesias", with fragrant funnel-shaped flowers, are cultivated hybrids of lots of Freesia kinds. Some other types are also expanded as ornamental plants.
These are herbaceous plant life which grow from a conical corm 1-2.5 cm size, which delivers 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 blossoms with six tepals. Many types have fragrant narrowly funnel-shaped flowers, although those previously put in the genus Anomatheca, such as F. laxa, have chiseled flowers. Freesias are used as food plants by the larvae of some Lepidoptera kinds including Large Yellow Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" derive from crosses made in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the green- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have bouquets ranging from white to yellow, green, red and blue-mauve. They are really mostly cultivated skillfully in holland by about 80 growers.[3] Freesias can be conveniently increased from seed. Because of the specific and pleasing scent, they are generally used in hands lotions, shampoos, candles, etc.[citation needed], however, the blossoms are mainly used in wedding bouquets. They can be planted in the semester in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature will not fall season below about -7 ?C (20 ?F)), and in the spring and coil in Zones 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other types of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it has flat rather than cup-shaped blossoms. Extensive 'forcing' of the bulb occurs in Half 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 variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply natural remedies) are plant life which have no continual woody stem above earth. Herbaceous plant life may be annuals, biennials or perennials. Annual herbaceous plants expire completely at the end of the growing season or when they may have flowered and fruited, plus they then expand again from seed. Herbaceous perennial and biennial crops may have stems that die by the end of the growing season, but elements of the plant endure under or near to the bottom from season to season (for biennials, before next growing season, when they bloom and pass away). New growth grows from living tissue staying on or under the ground, including origins, a caudex (a thickened part of the stem at ground level) 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 and most grasses. In comparison, non-herbaceous perennial plant life are woody crops which have stems above surface that remain alive during the dormant season and expand shoots another yr from the above-ground parts - these include trees, shrubs and vines.
