More than 300 species and an extremely large number of hybrids. Most kinds form attractive evergreen mats or tufts of grasslike green, gray-green, blue-green, or gray-blue leaves. Single, semidouble, or double flowers in white and shades of pink, rose, red, yellow, and orange; many have a rich, spicy fragrance. Main bloom period for most is spring into early summer; some kinds rebloom later in season or keep going into fall if faded flowers are removed. All kinds of dianthus thrive in light, fast-draining soil.
From Europe and Asia. Grows to 8–12 in. high, forming a loose mat to 1 ft. wide. Blossoms, about 3/4 in. wide with sharp-toothed petals, are borne at ends of forked flowering stems with short leaves. Colors include white and light or dark rose to purple, spotted with lighter colors. Blooms in summer, in just a few weeks from seed; sometimes again in fall. Useful, showy ground- or bank cover. Can tolerate half-day shade.
