Dianthus carthusianorum, commonly known as Carthusian pink, is a perennial wildflower native to Europe. It is recognized by its deep magenta to crimson flowers, tightly clustered at the tops of slender stems, and by its narrow, grass-like leaves. The species name refers to the Carthusian monks, who were historically associated with landscapes where the plant commonly grew, giving it a quiet cultural link to monastic Europe. Unlike many other pinks, its flowers are not strongly scented, but their intense color makes them highly distinctive in dry grasslands and open slopes.
