DIANTHUS

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.

Dianthus barbatus

Vigorous biennial often grown as an annual. From southern Europe. Grows to 20 in. high and 1 ft. wide, with sturdy stems. Leaves are flat, light to dark green. Dense clusters of white, pink, rose, red, purplish, or bicolored flowers, about 1/2 in. across, set among leafy bracts; not very fragrant. Sow seeds in late spring for bloom the following year. Double-flowered and dwarf strains are obtainable from seed. Indian Carpet is only 6 in. high. The Amazon series grows to 18–36 in. high.
