Dahlia is a genus of bushy, summer- and autumn-flowering, tuberous perennial plants native to Mexico, where they are the national flower. 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.

The Aztecs is a collective term used for all of the Pre-Columbian Mesoamerican peoples under the control of the Mexica, founders of Tenochtitlan, and their two principal allies, who built an extensive empire in the late Postclassic period in the 14th, 15th and 16th centuries in Central Mexico. ...

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). Year 1872 (MDCCCLXXII) was a leap year starting on Monday (link will display the full calendar) of the Gregorian Calendar (or a leap year starting on Wednesday of the 12-day slower Julian calendar). ... // In biology, hybrid has two meanings. ...

Polyploidy is the condition of some biological cells and organisms manifested by the presence of more than two homologous sets of chromosomes. ...
