Freesia is a genus of herbaceous perennial flowering plant life in the family Iridaceae, first referred to 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 indigenous to the eastern area of southern Africa, from Kenya south to South Africa, most species being found in Cape Provinces. Types of the previous genus Anomatheca are actually included in Freesia. The vegetation often called "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of lots of Freesia kinds. Some other species are also produced as ornamental crops.
They may be herbaceous plant life which grow from a conical corm 1-2.5 cm diameter, which transmits up a tuft of narrow leaves 10-30 cm long, and a sparsely branched stem 10-40 cm high 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 formerly positioned 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 Yellowish Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" are derived from crosses manufactured in the 19th hundred years between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these types and the red- and yellow-flowered forms of F. corymbosa. Modern tetraploid cultivars have flowers which range from white to yellow, green, red and blue-mauve. They may be mostly cultivated expertly in holland by about 80 growers.[3] Freesias can be immediately increased from seed. Because of their specific and satisfying scent, they are often used in hands ointments, shampoos, candles, etc.[citation needed], however, the blossoms are mainly utilized in wedding bouquets. They could be planted in the semester in USDA Hardiness Zones 9-10 (i.e. where the temperature does not fall below about -7 ?C (20 ?F)), and in the spring and coil in Zones 4-8.
Freesia laxa (formerly 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 includes flat rather than cup-shaped plants. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the light bulbs in proprietary solutions to satisfy cold dormancy which results in formation of buds in a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply herbal remedies) are plant life that contain no continual woody stem above earth. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants pass away completely at the end of the growing season or when they have got flowered and fruited, plus they then expand again from seed. Herbaceous perennial and biennial vegetation may have stems that die at the end of the growing season, but parts of the plant survive under or near the bottom from season to season (for biennials, before next growing season, when they flower and expire). New progress builds up from living cells staying on or under the ground, including root base, a caudex (a thickened part of the stem at ground level) or numerous kinds of underground stems, such as 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 which have stems above earth that stay alive during the dormant season and increase shoots another time from the above-ground parts - included in these are trees, shrubs and vines.
