Dianthus Plants

Low-growing plants with long-lasting blooms

Dianthus plants produce small but abundant flowers with fringed petals and a light, spicy fragrance. Most varieties bloom in spring, with many continuing into summer when regularly maintained. Their compact size makes them well suited for edging, containers, and mixed perennial plantings.

Is Dianthus Perennial?

Most dianthus plants are perennials, returning year after year in moderate climates. Some types behave as short-lived perennials or are grown as annuals in colder regions. Hardy perennial dianthus form neat mounds of evergreen or semi-evergreen foliage and bloom reliably in full sun.

Do Deer Eat Dianthus?

Dianthus are generally deer resistant. While no plant is completely deer-proof, the narrow foliage and light clove scent make dianthus less appealing to deer than many flowering plants. They are often a good choice for gardens where deer pressure is a concern.

How to Deadhead Dianthus

Deadheading dianthus helps extend the blooming period and keeps plants looking tidy. Remove spent flowers by trimming the flower stem back to the next set of healthy leaves. Regular deadheading encourages repeat blooms and prevents plants from putting energy into seed production.

How to Plant Dianthus

Dianthus plants grow best in full sun and well-drained soil. When planting dianthus, space plants to allow good air circulation and avoid heavy, wet soils. Water regularly during establishment. Once established, dianthus prefer drier conditions and require minimal care.

Where Dianthus Plants Work Best

Dianthus plants are commonly used for border edging, rock gardens, containers, and low-maintenance perennial beds. With their compact growth habit and long bloom time, dianthus add structure and color without overwhelming surrounding plants.
