Cultivation and History
Dianthus is a large genus in the family Caryophyllaceae, with over 300 species endemic to Asia, Europe, and Japan plus a North American alpine species. The genus name is derived from the Greek words dios (god) and anthos (flower), meaning “divine flower” or “flower of the gods.” Garden pinks or Dianthus plumarius is a species within the Dianthus genus and includes many cultivars that are grown in gardens and are suitable for landscape applications.
D. plumarius are also called common, cottage, Scotch, or wild pinks, and are native to central Europe, being introduced to the UK around the year 1100. A short-lived perennial evergreen, it has a mat-forming growth habit reaching 1- 2 feet tall and is hardy in Zones 4-9. Simple lancet leaves grow opposite one another on upright, branching stems in a subdued shade of glaucous gray green.
The pretty flowers grow in scapes of 3 to 5 buds and can be single, semi-double, or double petaled ranging in size from 1 to 2.5 inches – with the doubles typically offering the largest blooms. They come in tones of maroon, mauve, purple, pink, red, and white and have a seemingly infinite variety of color patterns, often with a striking eye of contrasting color.
Blooming from May to July, plumarius will re-bloom lightly after the first flush. Grown for their pretty, fringed flowers with a spicy fragrance of cloves, they’ve been cultivated for centuries. Numerous references to their popularity are found in European art works, tapestries, and the illuminated illustrations of Medieval texts and prayer books. And petals of D. plumarius were once added to wines and cordials to lend a spicy flavor – one of the oldest known cultivars is actually called ‘Sops in Wine’! Naming of the species is a little unclear. Some believe it comes from the German name for plants that bloomed at Pentecost called pfingsten. Others say it comes from the jagged petal edges, which look as though cut by pinking shears.
Regardless of the name origin, the color is named for the flower, and not the other way around. Until the eighteenth century, flowers in this shade were referred to as blush, carnation, flesh-colored, light or pale red, or rose, but never as “pink”.
Propagation
Garden pinks can be propagated by seed or by cuttings.
To grow from seed, start seeds indoors 6 to 8 weeks before the last frost in your region. Many cultivars are sterile and must be propagated by cuttings to ensure the same characteristics of the parent plant. This can be done with non-flowering cuttings taken in the summer.
How to Grow
Garden pinks grow best in a light, fluffy soil with a sandy, loamy texture and a neutral, or slightly limey, pH – but they don’t like to be in acidic soil. Add 4 to 6 inches of well-rotted manure or compost to enrich the soil before planting, and ensure the site is well-draining. Standing water in winter can be a problem and they need excellent drainage to prevent dieback. Add sharp sand to the planting site to improve drainage if needed. They require dry to medium moisture levels and full sun for a minimum of six hours per day – although they’ll appreciate some afternoon shade in very hot summer weather. And they can tolerate humidity, but ensure plants have proper air circulation to prevent fungal infections. Although perennial, they are short lived and will form bare patches in the center where the plant dies off. Plan on renewing them every 3 to 4 years. Because they’re so easy to propagate, starting a few cuttings each year is a good way to ensure your plants always survive the winter. D. plumarius also benefits from deadheading spent flowers which will encourage a second, lighter flush of blooms. In the garden, plants can be spaced 9 to 12 inches apart. In containers they can be closer, about 6 to 9 inches apart.
Growing Tips
Hardy in Zones 3-9, D. plumarius will appreciate a thick mulch in winter to protect it from cold and harsh winds. In colder regions, they can easily be grown from seed as an annual if started early indoors. Pinks have a sweet fragrance of cloves and make a wonderful, long-lasting cut flower – be sure to plant plenty to cut for indoor arrangements. Old-fashioned varieties will self-seed readily in optimum conditions – leave some seedheads in place if so desired. Replace every 3 to 4 years to keep plants looking vibrant. Plants are deer resistant.
Pruning and Maintenance
Garden pinks are easy to care for and will respond well to just a little TLC. Prompt deadheading of spent flowers will extend the bloom period and encourage new buds. For large plantings, shear the plants after blooming. This prevents self-seeding, trims the stems and foliage, and encourages a second, lighter flush of flowers. In regions with cold winters, provide a 4 to 6-inch layer of dry mulch such as hay, shredded leaves, or straw. In spring, once new foliage begins to emerge but before the flower buds, remove any mulch or winter debris. Remove any dead spots that developed over winter, then top and side dress plants with organic material such as aged compost or manure. Fluff the material before top dressing and rake material gently down to the roots.

Managing Pests and Problems
In areas with warm, humid summers or prolonged wet spells, leaf spot bacteria, Alternaria solani and Septoria lycopersici, can cause blight – brown, gray, tan, or yellow spots that first appear on foliage. Spider mites and aphids like to suck sap from dianthus and can be controlled with a good blast from the garden hose. Make sure to spray the underside of leaves to get all of them. Or, an insecticidal soap will dispatch most insects, as will a spray of neem oil. Adding ladybugs to the garden is another good way of controlling the smaller pest insects. Crown rot can also be a problem that shows up as wilt and dieback, and prevention is the best solution. Ensure your plants have excellent drainage, particularly in winter when standing water can cause damage. Thankfully, slugs, snails, and deer all find dianthus distasteful!
