Species of plant

Agave amica, once Polianthes tuberosa, the tuberose, is a perennial plant in the family Asparagaceae, subfamily Agavoideae, extracts of which are used as a eminence in perfumery. nowadays wide grown as an cosmetic plant, the species was primitively native to Mexico .

etymology [edit ]

The park name derives from the Latin tuberosa through french tubéreuse, [ 2 ] meaning well up or tuberous in mention to its beginning system.

description [edit ]

The tuberose is herbaceous, growing from underground tubers or tuberous roots. It produces offsets. The leaves are a dull green and about 1–1.5 ft ( 30–50 centimeter ) long and astir to 0.5 in ( 13 millimeter ) across-the-board at the base. They are slenderly lush. The blossoming is a spike, reaching up to 3 foot ( 1 megabyte ) high, with pure white waxen flowers. The flowers are tubular, with a metro up to 2.5 in ( 6 curium ) hanker, separating into six flaring segments ( tepals ) at the end, and are powerfully fragrant. There are six stamens, inserted into the tube of the flower, and a three-part mark. [ 3 ] The double-flowered cultivar ‘The Pearl ‘ has broader and dark leaves, and shorter flower spikes, normally reaching only 1.5–2 ft ( 50–60 centimeter ). orange-flowered forms of the species have been reported. [ 3 ]

taxonomy [edit ]

The species was first described for skill by Carl Linnaeus in 1753, as Polianthes tuberosa. [ 4 ] In 1790, Friedrich Kasimir Medikus moved the species to the genus Tuberosa as Tuberosa amica. [ 5 ] [ 1 ] Both morphologic and molecular phylogenetic studies have shown that Polianthes is embedded within the larger genus Agave, and the genus is now included in a broadly circumscribe Agave. [ 6 ] [ 7 ] Two incorrect attempts were made to name the species when transferred to Agave. In 1999, Joachim Thiede and Urs Eggli published the name “ Agave tuberosa “. however, Philip Miller had published this name in 1768, for the species now called Furcraea tuberosa, [ 8 ] so it can not be used again, and Thiede and Eggli ‘s name is bastard. In 2001, Thiede and Eggli published a substitute list ( nomen novum ), “ Agave polianthes “. however, since Medikus ‘s Tuberosa amica is considered to be a synonym of Polianthes tuberosa, its epithet is the second honest-to-god and according to the International Code of Nomenclature for alga, fungi, and plants should be used when the older epithet is unavailable. Hence Thiede and Eggli ‘s second base name is otiose, [ 9 ] and the right identify for the species within Agave is Agave amica, as was explained by Thiede and Rafaël Govaerts when they published this combination in 2017. [ 10 ]

distribution [edit ]

The tuberose is believed to be native to central and southerly Mexico. [ 1 ] It is no long found in the angry, probably as a result of being domesticated by the Aztecs. It is presently grown in many tropical and moderate countries. [ 3 ]

Uses [edit ]

In perfumery [edit ]

The overwhelm aroma of the tuberose has been distilled for use in perfumery since the seventeenth century, when the flower was first transported to Europe. french Queen Marie Antoinette used a perfume called Sillage de la Reine, besides called Parfum de Trianon, containing tuberose, orange flower, sandalwood, jasmine, iris and cedar. [ 11 ] [ 12 ] It remains a democratic floral note for perfumes, either in stand-alone Tuberose fragrances or assorted floral scents, but it generally must be used in moderation because the perfume is overpowering and can become ailing to the wearer. [ 13 ]

Others [edit ]

In India and Bangladesh they are widely used in making flower garlands which are offered to the gods or used as marry ornaments. [ citation needed ] While once associated with funerals, it is now used in floral arrangements for other occasions. [ 14 ] In Indonesia, tuberose flowers are besides used in cooking. [ 15 ] In Hawaii, they are one of the main flowers used in the construction of wreath. Some others are plumeria, ginger, orchids, and pikake ( jasmine ). [ 16 ]

cultivation [edit ]

Flowers of the double-flowered cultivar ‘The Pearl ‘

Tuberose seeds Tuberoses can be overwintered outdoors in boldness zones 8-10. [ 17 ] In cold zones, tuberoses are grown as summer annuals, in pots or mixed-flower borders where they can be enjoyed for their odorize. To flower the plants require around 4 months of affectionate temperatures from the time the rhizome is planted. Gardeners normally start the rhizomes in pots in greenhouses beginning in late-winter or early spring, moving them outdoors in late spring once frost danger has passed. [ 18 ] If they are started directly in the crunch at this time, they may not bloom until September, greatly reducing the time period in which their blooms may be enjoyed. Once the foliation begins to yellow in October, the leaves should be clipped, the rhizomes grok and stored in a cool, dry and dark place for the winter. [ 18 ] The most popular kind is a double-flowered cultivar known as ‘The Pearl ‘ that grows to 2.5 foot ( 76 centimeter ) tall and features pale pink buds opening to cream. [ 19 ] The more coarse assortment is called ‘Mexican Single ‘, which, although not ampere cosmetic as ‘The Pearl ‘, makes for a longer last cut flower. [ 18 ] Tuberoses were specially beloved by Louis XIV of France, who had them planted in the hundreds in the flower beds of the Grand Trianon at Versailles so that the odorize was overpowering, which no doubt helped cover the smells from the poor sanitation of the palace. They were grown in mud pots and planted immediately in the earth ; to keep the aroma systematically strong raw specimens were rotated in, sometimes casual.
