Description

"PInk Blush Dahlia" was taken while strolling through the flower gardens of the Chicago Botanical Gardens in Glencoe, Illinois this past summer. I am always looking for flowers to illustrate color, detail, and beautiful lighting.

This is a dahlia which is one of 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 2 inch in diameter or up to 1 foot. (dinner plate). This great variety results from dahlias being octoploids, that is, they have eight sets of homologous chromosomes, whereas most plants have only two. In addition, dahlias also contain many transposons (genetic pieces that move from place to place upon an allele) which contributes to their manifesting such great diversity.

The stems are leafy, ranging in height from as low as 12 inches to more than 6-8 feet. 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.
