Low-growing options in full sun include coreopsis, petunia, dianthus, pentas and marigold plants. Taller options to bridge the distance between the lower level plantings and a large butterfly bush include blazing star, catmint, heather, zinnia and agastache.
Several towering butterfly bushes at the back of a butterfly garden offer visual interest. Smaller butterfly favorites to plant in front of buddleia include coneflower, cosmos, lantana, bee balm, New England aster, phlox and milkweed.
Small sun-loving shrubs are right at home in front of butterfly bush. A foreground consisting of boxwood, dwarf crape myrtle, spirea, quince or creeping gardenia complement a yard in which Buddleia towers at the back.
