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. The stems are leafy, ranging in height from as low as
12 in (30 cm) to more than 6–8 ft. The majority of species do
not produce scented flowers or cultivars. Like most plants that do not attract pollinating
insects through scent, they are brightly colored, displaying most hues, with
the exception of blue.
