Dahlia White flower in the Garden. A member of the Asteraceae or Compositae, dicotyledonous plants, related species include the sunflower, daisy, chrysanthemum, and zinnia. There are 42 species of dahlia, with hybrids commonly grown as garden plants. Flower forms are variable, with one head per stem; these can be as small as 5 cm 2 in diameter or up to 30 cm 1 ft `dinner plate`. This great variety results from dahlias being octoploidsÃ¢â¬âthat is, they have eight sets of homologous chromosomes, whereas most plants have only two. In addition, dahlias also contain many transposonsÃ¢â¬âgenetic pieces that move from place to place upon an alleleÃ¢â¬âwhich contributes to their manifesting such great diversity.
