Dahlia is a genus of bushy, tuberous, herbaceous perennial
plants native mainly in Mexico, but also Central America, and Colombia. A
member of the Asteraceae or Compositae, dicotyledonous plants, related species
include the sunflower, daisy, chrysanthemum and zinnia. That same year, several
new species were reported with red, purple, lilac, and pale yellow coloring,
and the first true double flower was produced in Belgium. One of the more
popular concepts of dahlia history, and the basis for many different
interpretations and confusion, is that all the original discoveries were single
flowered types, which, through hybridization and selective breeding, produced
double forms. Many of the species of
dahlias then, and now, have single flowered blooms. Source
