Dahlias comprise a genus with at least 36 species of bushy plants that are native to the western regions of Central and South America. There are more than 20,000 named cultivars of these plants in captivity, which are the result of both hybridization and chromosomal duplication: Dahlias are octoploid -- possessing eight copies of each homologous chromosome, whereas most plants have only two copies of each chromosome.
