Cosmopolitan Garden Phlox Plant

Cosmopolitan Phlox is just one of the newer varieties from Dutch breeder Jan Verschoor and is part of his Cocktail Series, a line of more compact summer Phlox. Cosmopolitan has florets that are the most amazing shade of deep pink with lavender-blue veining and shading but with a striking red eye that lends intense interest to this garden Phlox. There is no doubt that gardeners will soon be shortening its name to Cosmo as it becomes a customer favorite in gardens across the U.S. Known to attract butterflies!
