This biennial beauty is a favorite of hummingbirds! Flowers comes in vivid shades of red, pink, white, and bi-color, sometimes with a contrasting eye, and with fringed petals that are bearded on the inside. A close relative of the carnation, these fragrant blooms make a spectacular display in any wildflower planting.
