Freesia is a genus of herbaceous perennial flowering vegetation 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 is local to the eastern area of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Species of the previous genus Anomatheca are actually included in Freesia. The vegetation commonly known as "freesias", with fragrant funnel-shaped bouquets, are cultivated hybrids of lots of Freesia types. Some other types are also grown as ornamental vegetation.
They can be herbaceous vegetation which expand 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 large bearing a few leaves and a loose one-sided spike of blooms with six tepals. Many types have fragrant narrowly funnel-shaped plants, 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 species 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 kinds and the pink- and yellow-flowered types of F. corymbosa. Modern tetraploid cultivars have blossoms ranging from white to yellow, red, red and blue-mauve. These are mostly cultivated skillfully in the Netherlands by about 80 growers.[3] Freesias can be immediately increased from seed. Because of the specific and desirable scent, they are generally used in hand ointments, shampoos, candles, etc.[citation needed], however, the blooms are mainly used in wedding bouquets. They could be planted in the land in USDA Hardiness Areas 9-10 (i.e. where the temperature will not fall season below about -7 ?C (20 ?F)), and in the springtime in Areas 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 offers flat somewhat than cup-shaped blooms. Extensive 'forcing' of the bulb occurs in Half Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy cool dormancy which results in formation of buds within a predicted variety of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous crops (in botanical use frequently simply natural remedies) are crops which have no continual woody stem above surface. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants pass away completely at the end of the growing season or when they may have flowered and fruited, and they then grow again from seed. Herbaceous perennial and biennial vegetation may have stems that pass away by the end of the growing season, but parts of the plant endure under or close to the ground from season to season (for biennials, until the next growing season, when they rose and pass away). New growth builds up from living tissues staying on or under the ground, including roots, a caudex (a thickened part of the stem at ground level) or various types 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 and most grasses. In comparison, non-herbaceous perennial crops are woody vegetation that have stems above floor that continue to be alive during the dormant season and develop shoots the next calendar year from the above-ground parts - these include trees, shrubs and vines.
