Dianthus Plant Profile
Dianthus (Dianthus spp.) is a flowering plant family that includes the familiar florist carnations. Dianthus are mainly native to Europe and Asia. They are also known as Sweet William or Pinks.
Dianthus can be annual or perennial. If perennial, they are generally hardy from zones 3 to 9.
The plants range from ground-hugging types to varieties that are two feet tall. The foliage and stems are a pretty blue-green and have a waxy feel to them. These long-lasting blooms make a terrific cut flower.
The flowers come in hues from white to pink to red. Many have splotches of accent colors in the center or interesting variegated patterns. The zig-zag or fringed edge of the flower petals is distinctive and sets them apart from most other blooms.
They have a spicy-sweet scent usually described as clove-like.
Dianthus prefers full to part sun and well-draining, alkaline soils. They do well in container plantings and rock gardens.
Remove the spent flowers to encourage re-blooming and fertilize them a few times during the growing season. Divide perennial Dianthus every few years in early spring.
