JC Raulston Arboretum at NC State University

Family

Caryophyllaceae

Botanical Name

DIANTHUS 'Little Boy Blue'( Allwoodii Alpinus Group)

Plant Common Name

Alpine Dianthus, Little Boy Blue Alpine Dianthus

General Description

The Dianthus Allwoodii group comprises numerous semi-evergreen, cushion-forming perennials resulting from crossing Dianthus pulmaris (cottage pink) with perpetual-flowering carnations. The cultivar 'Little Boy Blue' bears many clove-scented, frilly white flowers with pink eyes in late spring and early summer above mounds of grassy, blue-green leaves. Sporadic rebloom may occur in summer and early fall.

Preferring full sun and well-drained, neutral soil, this pink is well suited to rock gardens, border fronts, or containers. It needs division every 2 or 3 years to maintain its vigor.
