Freesia is a genus of herbaceous perennial flowering crops 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 is indigenous to the eastern side of southern Africa, from Kenya south to South Africa, most kinds being within Cape Provinces. Types of the past genus Anomatheca are now contained in Freesia. The plant life often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of lots of Freesia types. Some other species are also expanded as ornamental vegetation.
They are herbaceous crops which grow from a conical corm 1-2.5 cm diameter, which directs up a tuft of small 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 flowers with six tepals. Many types have fragrant narrowly funnel-shaped blooms, although those previously put in the genus Anomatheca, such as F. laxa, have even 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" derive from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these species and the green- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blossoms which range from white to yellow, pink, red and blue-mauve. They can be mostly cultivated professionally in holland by about 80 growers.[3] Freesias can be commonly increased from seed. Because of the specific and desirable scent, they are often used in hands creams, shampoos, candles, etc.[citation needed], however, the blooms are mainly utilized in wedding bouquets. They can be planted in the fall season in USDA Hardiness Zones 9-10 (i.e. where in fact the temperature does 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 species of the genus which is often cultivated. Smaller than the scented freesia cultivars, it offers flat rather than cup-shaped blossoms. Extensive 'forcing' of this bulb occurs in two Moon Bay in California where several growers chill the lights in proprietary solutions to satisfy chilly dormancy which results in development of buds inside a predicted number of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous plants (in botanical use frequently simply herbs) are crops which have no persistent woody stem above earth. Herbaceous plant life may be annuals, biennials or perennials. Total annual herbaceous plants die completely at the end of the growing season or when they have flowered and fruited, and they then increase again from seed. Herbaceous perennial and biennial plant life may have stems that pass away at the end of the growing season, but elements of the plant endure under or near to the ground from season to season (for biennials, before next growing season, when they bloom and pass away). New progress evolves from living tissues left over on or under the bottom, including origins, 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 vegetation are woody vegetation which have stems above ground that stay alive through the dormant season and grow shoots the next 12 months from the above-ground parts - included in these are trees and shrubs, shrubs and vines.
