Dianthus, commonly known as Pinks, is a genus of flowering plants from the Caryophyllaceae family. Originating from Europe and Asia, these perennials add a burst of color and fragrance to gardens and are known for their versatility, resilience, and captivating appearance. Whether adorning flower beds, rock gardens, or borders, Dianthus plants have earned a reputation for their enchanting blooms and ease of cultivation.
Growing and Caring For Dianthus
The first step in successfully cultivating Dianthus is selecting an appropriate location. These plants thrive in well-drained soil with a slightly alkaline to neutral pH. Choose a sunny spot, as Dianthus favors full sun, though they can tolerate partial shade. Adequate sunlight ensures robust growth and vibrant blooms. Once the planting site is chosen, prepare the soil by adding organic matter, such as compost, to enhance fertility.
Watering is important during the initial establishment phase, but Dianthus is drought-tolerant once established. Overwatering should be avoided, as it can lead to root rot. Mulching around the plants helps retain moisture, suppress weeds, and maintain a consistent soil temperature. Regular deadheading encourages continuous blooming and prolongs the overall flowering period. In colder climates, providing a layer of mulch in late fall helps protect the plant during winter.
Dianthus plants are not heavy feeders, and excessive fertilization can lead to leggy growth. A balanced, slow-release fertilizer applied in spring is usually sufficient. Pruning is an essential aspect of Dianthus care. Trimming back the plants after the first flush of blooms encourages a second round of flowering and helps maintain a tidy appearance. Pinching off the growing tips during the growing season can lead to bushier, more compact plants.
Leaves and Flowers
Dianthus plants are characterized by slender, grass-like leaves that form tufts at the base. These linear leaves provide an attractive backdrop for the star attraction – the colorful, fragrant flowers. The flowers come in various hues, including shades of pink, red, white, and even bi-colored varieties. The blossoms are often characterized by a fringed or serrated edge, adding a touch of delicacy to their appearance. Some species, like Dianthus barbatus (Sweet William), produce tight clusters of small flowers, while others, like Dianthus caryophyllus (Carnation), boast larger, solitary blooms.
Common Uses in Gardening and Landscaping
Dianthus serves various purposes in gardening and landscaping, contributing both aesthetic and functional benefits. One of the most common uses is as a border plant, where the compact size and profusion of blooms create a stunning edge for flower beds or pathways. Dianthus is also well-suited for rock gardens, adding a pop of color amidst the stones and complementing the natural surroundings.
Container gardening enthusiasts appreciate Dianthus for its adaptability to pots and planters. The controlled environment of containers allows for easy placement on patios, balconies, or even windowsills, bringing the beauty of Dianthus to smaller spaces. These plants are also employed in mass plantings to create eye-catching swaths of color.

These perennial Dianthus are cold hardy and we usually start to see them around Valentines Day. Many of the varieties will bloom all season if deadheaded, and the majority of the perennial varieties are evergreen (or ever grey or ever blue, depending on the foliage color) in the Upstate.
We normally have 1-3 varieties of 4″ Dianthus on each of our color tables in Perennials at any given time, for about 15 flats, more or less, during spring and early summer. The varieties taper in the fall and winter, but we almost always have some 4″ Dianthus in stock. We also do carry dianthus in 6″ and 1-gallon containers but these are inconsistently stocked. In our annual flat section, we carry upright Dianthus (the Ideal Select series) annuals in flats and 4-packs.
Is Dianthus A Perennial?
Dianthus encompasses both perennial and annual species, providing gardeners with diverse options to suit their preferences and climate conditions. At Martin Garden Center, we treat Dianthus as a perennial.
Do Deer Eat Dianthus?
Dianthus is known for its aromatic foliage, and the scent is often a natural deterrent for deer. Deer tend to avoid plants with strong fragrances, and Dianthus falls into this category with its spicy or clove-like scent. While these blooms are often spared from the ravenous appetite of deer, a curious deer may indulge in a nibble, particularly if hunger strikes or temptation beckons.
How Do I Prevent My Dianthus From Becoming Leggy?
Regular pruning and deadheading are effective measures to prevent Dianthus from becoming leggy. Pinch back the growing tips during the growing season to promote bushier growth and maintain a more compact form.
Do Rabbits Eat Dianthus?
While dianthus is not typically their top choice, rabbits have been known to snack on dianthus plants, especially if other food sources are limited or if they find themselves particularly tempted by the tender foliage or blooms. Like many animals, rabbits may sample various plants based on availability, season, and individual preference. To safeguard your dianthus from rabbit munching, employing protective measures such as fencing, repellents, or planting rabbit-resistant species can help maintain your garden’s beauty.
