Dianthus pavonius aka Peacock Eye Pink

Dianthus pavonius is an evergreen perennial in the pink family, Caryophyllaceae. Gardeners call it peacock pink or grass rose pink. Kew and the RHS place its native range in the southwestern Alps. NC State also describes wild plants in the Pyrenees. It grows in sunny grasslands and on rocky mountain slopes. These habitats suit its low, close-knit form.

The plant forms a dense cushion or grass-like mat. Garden heights range from about 0.3–0.5 feet (0.1–0.15 metres). Its spread reaches about 0.3–1 foot (0.1–0.3 metres). The RHS gives the smaller size; NC State gives the larger. Pointed leaves stay on the plant through winter. Their colour ranges from green to grey-green or dark blue-green. Flower stems reach about 0.3 feet (0.1 metres) tall. Each stem carries one to three blooms above the leaves.

The scented flowers open from late April into June. Their petals range from pale pink to deep pink. The backs of the petals have a buff tint. Each flower measures about 0.07 feet (0.02 metres) across. The petals have toothed edges and a bearded surface. Blue or brown centres add contrast to the pink blooms. After flowering, cylindrical capsules hold the brown seeds. Removing spent flowers can extend the flowering season.

Grow this pink in full sun with good soil drainage. Loam and sandy soil both suit it. NC State favours rich, gritty loam with even moisture. Once established, the plant can withstand drought. Sources differ on the best soil pH. The RHS recommends acid to neutral soil. NC State favours neutral to slightly alkaline conditions. The RHS rates it H7 for cold hardiness. NC State lists USDA zones 5–8. Plants reach their full size in two to five years. They need no routine pruning.

Its small size suits rock gardens, crevices, and border fronts. It also fits containers, gravel beds, slopes, and rock walls. Deer and rabbits tend to leave it alone. Aphids and slugs may attack it, though NC State reports few serious problems. Possible diseases include rust, powdery mildew, viral disease, and fusarium wilt. Sow seeds in a cold frame from autumn through early spring. Summer cuttings can use non-flowering shoots. This is not a plant to treat as food. Eating the leaves may cause mild stomach upset. Contact can cause skin irritation in people and pets. Wear gloves when handling it.
