Growing Dianthus

Plant it in full sun. It prefers low water. It is hardy in USDA zones 3–9. Expect it to reach about 12 in tall and 12 in wide at maturity, in roughly 2 years.

When to plant Dianthus

Plant Dianthus in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. For the middle of its hardy zones 3 to 9 range, spring means March to May and fall means August or September. Once settled, it blooms from May to August.

Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 6 in March.

Good to know about Dianthus

Curated from university extensions, botanic gardens and other primary sources, with the source named on every note.

Safety

Mildly toxic to dogs and cats: an unknown irritant causes mild stomach upset, and the leaves' saponins can cause mild skin dermatitis in sensitive people. per ASPCA and NC State

Worth knowing

The name 'pinks' comes from the fringed, toothed petal edges, as if trimmed with pinking shears, not from the color. Many are strongly clove-scented. per NC State

Rabbit resistance is uncertain

The species pages and Wisconsin call garden pinks rabbit resistant, but NC State's genus page lists them as vulnerable. Deer resistance is unanimous; rabbit protection is not. per NC State and Wisconsin

The main killer

Crown and root rot in wet, poorly drained soil is the main way garden pinks are lost. Sharp drainage and drying between waterings largely prevent it. per NC State

Short-lived; divide to renew

Garden pinks are short-lived and open up after a few years. Dividing the clumps every 2 to 3 years, in early spring, keeps them vigorous and floriferous. per NC State

Deer resistant

Consistently rated deer resistant across sources: the aromatic, sharp-tasting foliage deters browsing, so deer leave it alone. per NC State

Draws bees and butterflies

The fragrant, nectar-bearing flowers attract bees and butterflies; cheddar pink also draws moths and cottage pink is visited by hummingbirds. A modest but genuine pollinator plant. per NC State

What pairs well with Dianthus

Good companions share its growing conditions and add something it lacks: an earlier or later bloom, a lower carpet in front, or structure through winter.
