In Greek, Dianthus is translated as “heavenly flower” or “flower of Zeus.” These understated, softly fragrant blooms add elegance to rock gardens, containers, and borders. Imagine them growing along the rocky cliffs of Mount Olympus! Most Dianthus are classified as herbaceous perennials, although some are annuals or biennials; pick a spot with well-draining soil and at least six hours of sun and they will thrive.
