Hyacinth (plant)

Hyacinthus is a small genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae, that are commonly called hyacinths /ˈhaɪəsɪnθs/. The genus is native to the eastern Mediterranean (from south Turkey through Lebanon and Syria to northern Israel/Palestine), Iraq, north-east Iran, and Turkmenistan.

Several species of Brodiea, Scilla, and other plants that were formerly classified in the lily family and have flower clusters borne along the stalk also have common names with the word "hyacinth" in them. Hyacinths should also not be confused with the genus Muscari, which are commonly known as grape hyacinths.

Description

Hyacinthus grows from bulbs, each producing around four to six linear leaves and one to three spikes or racemes of flowers. In the wild species, the flowers are widely spaced with as few as two per raceme in H. litwinovii and typically six to eight in H. orientalis, which grows to a height of 15–20 cm (6–8 in). Cultivars of H. orientalis have much denser flower spikes and are generally more robust.

Zircon

Zircon (/ˈzɜːrkɒn/ or /ˈzɜːrkən/; including hyacinth or yellow zircon) is a mineral belonging to the group of nesosilicates. Its chemical name is zirconium silicate and its corresponding chemical formula is ZrSiO₄. A common empirical formula showing some of the range of substitution in zircon is (Zr_1–y, REE_y)(SiO₄)_1–x(OH)_4x–y. Zircon forms in silicate melts with large proportions of high field strength incompatible elements. For example, hafnium is almost always present in quantities ranging from 1 to 4%. The crystal structure of zircon is tetragonal crystal system. The natural color of zircon varies between colorless, yellow-golden, red, brown, blue, and green. Colorless specimens that show gem quality are a popular substitute for diamond and are also known as "Matura diamond".

The name derives from the Persian zargun meaning golden-colored. This word is corrupted into "jargoon", a term applied to light-colored zircons. The English word "zircon" is derived from "Zirkon," which is the German adaptation of this word. Red zircon is called "hyacinth", from the flower hyacinthus, whose name is of Ancient Greek origin.

Hyacinthus orientalis

Hyacinthus orientalis (common hyacinth, garden hyacinth or Dutch hyacinth), is a herbaceous perennial flowering plant, native to southwestern Asia, southern and central Turkey, northwestern Syria, Lebanon and northern Israel. It was introduced to Europe in the 16th century. It is widely cultivated everywhere in the temperate world for its strongly fragrant flowers which appear exceptionally early in the season, and frequently forced to flower at Christmas time.

Description

It is a bulbous plant, with a 3–7 cm diameter bulb. The leaves are strap-shaped, 15–35 cm long and 1–3 cm broad, with a soft, succulent texture, and produced in a basal whorl. The flowering stem is a spike, which grows to 20–35 cm (rarely to 45 cm) tall, bearing 2–50 fragrant purple flowers 2–3.5 cm long with a tubular, six-lobed perianth.

Mythology

In Greek mythology, Hyakinthos was a young man admired by Apollo and Zephyr, but killed by a discus in a jealous fight between the two gods; a flower was allegedly named after him when it sprang from his blood. However, Theophrastus describes both a cultivated and a wild plant called ὑάκινθος (hyakinthos), neither of which are considered to be the modern hyacinth.

Plant

Plants, also called green plants, are multicellular eukaryotes of the kingdom Plantae. They form an unranked clade Viridiplantae (Latin for green plants) that includes the flowering plants, conifers and other gymnosperms, ferns, clubmosses, hornworts, liverworts, mosses and the green algae. Green plants excludes the red and brown algae, the fungi, archaea, bacteria and animals.

Green plants have cell walls with cellulose and obtain most of their energy from sunlight via photosynthesis by primary chloroplasts, derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic and have lost the ability to produce normal amounts of chlorophyll or to photosynthesize. Plants are also characterized by sexual reproduction, modular and indeterminate growth, and an alternation of generations, although asexual reproduction is also common.

Precise numbers are difficult to determine, but as of 2010, there are thought to be 300–315 thousand species of plants, of which the great majority, some 260–290 thousand, are seed plants (see the table below). Green plants provide most of the world's molecular oxygen and are the basis of most of the earth's ecologies, especially on land. Plants that produce grains, fruits and vegetables form mankind's basic foodstuffs, and have been domesticated for millennia. Plants are used as ornaments and, until recently and in great variety, they have served as the source of most medicines and drugs. The scientific study of plants is known as botany, a branch of biology.

Plantà

The plantá (which comes from the verb to plant; in Valencian, plantà) is the act of erecting a Falla or bonfire monument, in the Fallas or the Bonfires of Saint John, festivals held respectively in March and June in different localities of the Community of Valencia (Spain).The plantà is currently considered the exact moment when the falla or bonfire is completely finished and ready to be visited, with all its “ninots” (human figures made of combustible materials, such as cardboard or wood, which has a critical or mocking nature), posters and a variety of features (lights, matted grass, interpretive signs...).

In the Fallas of Valencia, the plantá takes place on March 15, when all the Falla monuments must be positioned correctly. The reason is that the jury appointed by the Central Fallera committee has to go to the next day to assess the falla. Formerly, the plantà began and ended the same day but, due to the complexity of the monuments and the fact that the makers of Fallas are responsible for several Fallas monuments at the same time, it usually begins a few days before. The burning of the Falla or cremá is carried out four days later, on the night of March 19.
