General Description

Delicate and fleeting on their own, the light yellow flowers of the hairy garden pink or yellow dianthus are a curiousity, evoking a meadow wildflower aesthetic. A small, tufted herbaceous perennial that sends up tall, thin flower stems in summer, it is native to the highlands of Hungary in southcentral Europe.

The narrow green to slightly gray-gren leaves look like needles and are on held upon upright, four-sided stems. In early or midsummer, thin stems lightly branch to hold a small cluster of flat but radial, jagged edged flowers that are light yellow to creamy ivory with purplish stamens. They have no fragrance. Seeds are produced readily and seedlings will volunteer in the immediate area.

Grow hairy garden pink in full to partial sun in a cool, moist but well-draining soils that is all but acidic. Gritty and sandy soils are ideal once some organic matter is incorporated. Do not overwater. The flower color is more yellow in areas with cool summers as high temperatures will make the flowers pale and also shorten the lifespan of the plant. Overall, this species is not extraordinary, but surely a curiousity. Its claim to fame is that it is used in breeding in order to produce yellow-flowering carnations. Selection 'Yellow Harmony' has slightly larger flowers and is a bit less weed-like in its appearance.
