Георгин

From Wikipedia:
Георгины (Dahlia Cav.) — род растений из семейства сложноцветных (Compositae). Сюда относятся 9 весьма крупных многолетников с большими головками цветов, иногда шаровидными. У дикорастущих американских видов головка соцветия всегда состоит из цветков двух родов: по краям всего соцветия расположены язычковые, или неплодящие, цветки (как у подсолнечника), обычно белого цвета, а в середине (в диске) мелкие трубчатые жёлтые цветки, приносящие плоды. В наших садах эти формы встречаются изредка; но огромное большинство георгин всех оттенков относится к массе садовых разновидностей и махровых пород, у которых все срединные цветки превращены культурой в неплодящие язычковые, вследствие чего все соцветие делается плотнее, полнее, доходя до шарообразной формы и крайне различных тонов окраски, нередко даже с пёстрыми цветами. Из дикорастущих в Америке видов георгин следует указать на Dahlia imperialis Rz., достигающую до 6 метров высоты; цветы у ней двоякие: краевые — белые, неплодные, в небольшом числе, а срединные — жёлтые, плодящие; листья сложные. Самым же распространённым по всей Европе (в садах) видом являются многочисленные формы Dahlia variabilis Desf. (георгина переменчивая), которая в диком виде имеет разноцветные краевые (язычковые) цветы и жёлтые в середине (трубчатые); из этого-то вида и развились во множестве форм современные георгины, цветущие в конце лета и осенью. Они ввезены в Европу около 100 лет тому назад. У плодящих цветов по отцветании образуется плодик — семянка, сжатая со спинки и несущая наверху хохолок в виде невысокого неровного колечка. Листья простые, попарно сидящие; цветки (то есть головки или соцветия) на длинных ножках в углах листьев. Разводятся исключительно клубнями от корней; эти клубни весьма богаты особым полукристаллическим веществом кнулином, близким к крахмалу.

Латинское название растения, далия (dahlia) дано цветку по имени шведского ботаника 18 века Андерса Даля (Anders Dahl). Название "георгин" дано цветку ботаником Карлом Людвигом Вильденовом в честь петербургского академика-натуралиста Иоганна Готлиба Георги.

Dahlia

From Wikipedia:
Dahlia is a genus of bushy, tuberous, perennial plants native to Mexico, Central America, and Colombia. There at least 36 species of Dahlia. Dahlia hybrids are commonly grown as garden plants. The Aztecs gathered and cultivated the dahlia for food, ceremony, as well as decorative purposes [1], and the long woody stem of one variety was used for small pipes.

In 1872 a box of Dahlia roots were sent from Mexico to the Netherlands. Only one plant survived the trip, but produced spectacular red flowers with pointed petals. Nurserymen in Europe bred from this plant, which was named Dahlia juarezii with parents of Dahlias discovered earlier and these are the progenitors of all modern Dahlia hybrids. Ever since, plant breeders have been actively breeding Dahlias to produce thousands of cultivars, usually chosen for their stunning and brightly coloured flowers. Dahlia plants range in height from as low as 12" (30cm) to as tall as 6-8 feet (180-240cm). The flowers can be as small as 2" (5 cm) or up to a foot (30 cm) in diameter. The great variety results from Dahlias being octoploids (they have eight sets of homologous chromosomes, whereas most plants have only two).

Dahlias are used as food plants by the larvae of some Lepidoptera species including Angle Shades, Common Swift, Ghost Moth and Large Yellow Underwing.

The dahlia is named after Swedish 18th-century botanist Anders Dahl. Until recently they were also named in Germany as "georgine" by the botanist Carl Ludwig Willdenow, after the naturalist Johann Gottlieb Georgi of St. Petersburg.
