Dianthus deltoides (dy-AN-thus del-TOY-deez)

Family: Caryophyllaceae Non-native Herbaceous (1-3 ft)

Dianthus deltoides , commonly known as maiden pink, is a flowering plant in the Caryophyllaceae or carnation family. The species, deltoides, means the Greek letter delta (Ξ”), possibly referring to the narrowly triangular leaves. Maiden Pink is native to Europe and western Asia but has since been introduced to the United States where it can be found in the upper midwest of the United States and all of Canada. It is an herbaceous perennial that blooms from May to July, preferring well-drained soils in full sun. This plant provides excellent groundcover for landscapes as it produces many blooms in shades of red, pink, lavender or white with a darker star-like ring near the center. Problems: Leaf spot can infect plants in humid summers, where plants are crowded. Crown rot can be a problem when planted in wet, poorly drained soils. Good drainage is essential to avoid disease and die out in the center. Division is recommended every 2-3 years for healthy plants and to avoid overcrowding.
