Dianthus knappii 'Yellow Harmony' is an unusual Dianthus with soft yellow, single blooms that are paler in heat and darker in cooler weather. Also know as Pinks, the common name refers to the zigzag petal edges, not the color. The dainty blooms arise in small clusters on narrow stems above blue-green grassy foliage. Unlike most perennial Dianthus, 'Yellow Harmony' has little or no scent. Flowering primarily in May-July, the blooms are suitable for cutting.
Dianthus knappii, 'Yellow Harmony' prefers full sun and well-drained soil, particularly in winter. The flowers of 'Yellow Harmony' are larger than those of the straight species.
