DIANTHUS knappii 'Yellow Harmony'

Family

Caryophyllaceae

Botanical Name

DIANTHUS knappii 'Yellow Harmony'

Plant Common Name

Dianthus, Yellow Harmony Pink

General Description

‘Yellow Harmony’ features unique flowers of pale, creamy yellow which bloom atop slender, branched stems in summer. A selection of a species native to the highlands of Yugoslavia and Hungary, it offers larger flowers and tidier, more upright growth than its parent. Its single, fringed blossoms are borne on airy stems emerging from basal tufts of narrow, pointed, blue-green leaves, and bloom from late spring to midsummer. The flowers bear little to no fragrance, and tend to be more deeply colored in cooler temperatures, ranging more towards ivory in hotter climates.

Plant this distinctive perennial in full to part sun and gritty, well-drained, neutral to alkaline soil of average fertility. Offering good drought tolerance, it should not be subjected to overwatering and soggy conditions, as these may lead to stem and root decay. Although sometimes short-lived, the plants typically bloom in the first year from seed, and may propagate themselves if allowed to self-sow. ‘Yellow Harmony’ looks lovely tucked among stones in rock gardens, and is also ideal for meadow plantings. Its subtle blossoms are a charming, long-lived addition to casual flower arrangements.
