Quick Overview:

‘Concord Grape’ is a compact, clump-forming cultivar which typically grows to 12″ tall. Purplish-blue (concord grape), three-petaled flowers (to 1.5″ diameter) accented by contrasting yellow stamens are borne in terminal clusters (umbels) atop stiff stems. Numerous flower buds form in each cluster, but individual flowers open up only a few at a time, each for only one day, blooming in succession from May into August. Arching, iris-like, smoky, bluish-green leaves are folded lengthwise forming a groove.  (Courtesy of Missouri Botanical Garden Plant Finder)


Easily grown in average, medium to wet, well-drained soil in full sun to part shade. Prefers moist, acidic, humusy soils. Tolerant of wet, boggy soils. Deadhead each flower cluster after all buds in the cluster have opened to extend the bloom period. As the heat of the summer sets in, foliage tends to decline considerably and flowering slows down or stops entirely, at which point plants should be cut back hard. Cutting back plants almost to the ground will promote both new foliage growth and an additional late summer to fall bloom. Divide clumps when they become overcrowded.  (Courtesy of Missouri Botanical Garden Plant Finder)
