Are Dianthus annuals or perennials?
Dianthus chinensis is most often grown as a cool-season annual flower. However, it can be a short-lived perennial in Zones 5 and warmer. Its common name comes not from the pink color of its flowers but rather from the jagged edge of the flower petals, which look as though they have been cut with a pinking shear.
If you're wondering whether dianthus are annual or perennial, the genus Dianthus has species that are both annual and perennial-and also biennial. Here are some of the common names you may have heard associated with the genus. Pinks are perennial forms. They are evergreen or semi-evergreen.
Dianthus (commonly known as carnations or pinks) are an easy to care for perennial or annual plant. The flowers are ruffled at the ends, and sometimes have a very strong and spicy fragrance to them. The plants bloom during the summer and some can rebloom into the fall.

Dianthus should be planted in full sun, but can tolerate some shade. Well-drained soil and good air circulation are necessary to avoid diseases. Improve the soil drainage, if necessary.
Yes, when grown in temperate climates that have well-draining soil, the dianthus will return each year.
Depending on the species and cultivar, biennial and perennial dianthus are hardy in U.S. Department of Agriculture plant hardiness zones 3 through 10. Biennials and perennials will come back for at least two years, and nearly all the Dianthus species will reseed and produce new plants the following spring.
Protecting Dianthus in Winter
Protect your dianthus plants in the winter by covering them with a thick layer of organic mulch. This can be shredded leaves or bark mulch. If your plants do become covered by snow, this added layer of insulation will help protect them and keep them from freezing.
Dianthus plants come in all shapes and sizes. Miniature varieties form a tight little lump of foliage and blooms. Giant species reaching up to 3 feet tall have almost no basal foliage. These plants are typically mat-forming perennials that have very tight-knit spreads of foliage.
- Pinch off the spent flowers as they fade and wilt. ...
- Cut back mounding dianthus varieties after the first flush of flowering completes in early summer. ...
- Trim or pinch back overgrown and leggy stems at any time during the summer growing season to maintain the shape of the plant.

As long as they are planted in well-drained soil, they tolerate heat and thrive where rainfall and humidity are high. Dianthus flowers bloom prolifically in early spring and summer, but many dianthus will rebloom throughout the gardening season if you cut flowers off as they fade.
Removing dead blooms, before they have a chance to go to seed, encourages the plant to re-bloom. Dianthus, also commonly called carnation or sweet William, should be deadheaded with pruning shears. Because dianthus may re-bloom on each stem, it requires a bit of caution when deadheading.
Pinks (Dianthus plumarius) multiply easily and are deer resistant. The fragrant blossoms come in many colors and make excellent cut flowers. For earliest blooms start Pinks (Dianthus) seeds indoors six to eight weeks before your last frost. When started indoors, they will usually bloom the first year.
Too much moisture in the planting bed leads to root rot and fungal diseases, so make sure the soil has good drainage. Prepare the bed by turning the soil to a depth of 12 inches and add 2 to 4 inches of compost. Some plants can tolerate moist but not wet soil, but others require excellent drainage.
Wait until the danger of frost has passed when planting dianthus and place them at the same level they were growing in the pots, with 12 to 18 inches (30-46 cm.) between the plants. Do not mulch around them. Water them only at the base of the plant to keep the foliage dry and prevent mildew spotting.
Cutting Back Dianthus For Winter
When your plants are finished blooming for the season in the fall, you can cut them back to ground level. Do not worry about damaging your plants; a good cutting will help them put all of their energy into developing a strong root system and surviving the winter.
Dianthus plants come in all shapes and sizes. Miniature varieties form a tight little lump of foliage and blooms. Giant species reaching up to 3 feet tall have almost no basal foliage. These plants are typically mat-forming perennials that have very tight-knit spreads of foliage.
Grow pinks in well-drained compost in full sun. Cut back after flowering to encourage a second flush of blooms, and feed with a liquid tomato feed. Cut back again in autumn. Dianthus are not long lived plants – after a few years they go woody at the base and look rather straggly.
