There are at least 36 species of the dahlia, a perennial and a member of the asteraceae family, and they are prized for the texture and variety of their blooms. The genus is native to Mexico and Central America, with many subsequent hybrids. This great variety results from dahlias being octoploids: they have eight sets of chromosomes while most plants have only two, according to Wikipedia. These are in the garden of John Conner in Marina del Rey.
