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 known as after German botanist and doctor Friedrich Freese (1794-1878). It is indigenous to the eastern aspect of southern Africa, from Kenya south to South Africa, most kinds being found in Cape Provinces. Kinds of the former genus Anomatheca are actually contained in Freesia. The plants often called "freesias", with fragrant funnel-shaped plants, are cultivated hybrids of lots of Freesia kinds. Some other kinds are also grown as ornamental crops.
They may be herbaceous plants which expand from a conical corm 1-2.5 cm size, which transmits 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 plants with six tepals. Many types have fragrant narrowly funnel-shaped blooms, although those formerly put in the genus Anomatheca, such as F. laxa, have even flowers. Freesias are used as food plant life by the larvae of some Lepidoptera varieties including Large Yellowish Underwing.
CULTIVATION AND USES
The plant life usually called "freesias" are derived from crosses manufactured in the 19th century between F. refracta and F. leichtlinii. Numerous cultivars have been bred from these kinds and the pink- and yellow-flowered varieties of F. corymbosa. Modern tetraploid cultivars have blossoms ranging from white to yellow, pink, red and blue-mauve. They can be mostly cultivated expertly in the Netherlands by about 80 growers.[3] Freesias can be readily increased from seed. Because of the specific and desirable scent, they are generally used in hands lotions, shampoos, candles, etc.[citation needed], however, the plants are mainly used in wedding bouquets. They can be planted in the semester in USDA Hardiness Areas 9-10 (i.e. where the temperature does not show up below about -7 ?C (20 ?F)), and in the spring in Areas 4-8.
Freesia laxa (previously called Lapeirousia laxa or Anomatheca cruenta) is one of the other varieties of the genus which is commonly cultivated. Smaller than the scented freesia cultivars, it has flat somewhat than cup-shaped blooms. Extensive 'forcing' of the bulb occurs in two Moon Bay in California where several growers chill the light bulbs in proprietary solutions to satisfy frigid dormancy which results in formation of buds inside a predicted range of weeks - often 5 weeks at 55 ?F (13 ?C).
Herbaceous vegetation (in botanical use frequently simply herbs) are plants which may have no persistent woody stem above floor. Herbaceous crops may be annuals, biennials or perennials. Annual herbaceous plants perish 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 plant life may have stems that die by 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 blossom and pass away). New progress produces from living cells left over on or under the ground, including origins, a caudex (a thickened part of the stem at walk out) or various types of underground stems, such as lights, corms, stolons, rhizomes and tubers. Examples 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 crops are woody vegetation which have stems above surface that stay alive through the dormant season and expand shoots another year from the above-ground parts - included in these are trees, shrubs and vines.
