Dianthus caryophyllus, commonly known as the carnation or clove pink, is a species of flowering plant in the family Caryophyllaceae, native to the Mediterranean region. It is a herbaceous perennial that typically grows to a height of 30–80 cm (12–31 inches). The plant is characterized by its slender, grayish-green leaves, which are opposite, linear, and slightly fleshy, giving it a distinctive appearance.

The flowers of Dianthus caryophyllus are its most notable feature, often borne singly or in small clusters at the ends of the stems. They have a tubular calyx with five lance-shaped teeth and petals that are broadly obovate, often with fringed or serrated edges. The blooms come in a wide range of colors, including pink, red, white, yellow, and sometimes bicolored varieties, emitting a sweet, spicy fragrance reminiscent of cloves. Flowering typically occurs from late spring to summer, though in cultivation it can be extended with proper care.
