Tradescantia (Spiderwort) ‘Concord Grape’

Concord Grape’ is delightful with its deep, rich purple flowers and prominent yellow stamens. This American hybrid selection has beautiful narrow foliage in a unique frosty-blue shade, forming a compact mound that is studded with a summer-long display of small, triangular flowers. This is a prolific bloomer all summer if old blooms are removed. Trim back in midsummer if plants get scruffy. Clumps may be easily divided in early spring. Spiderworts appreciate a moist, rich soil, and will even tolerate wet sites beside a stream or pond. Tradescantia ‘Concord Grape’ is attractive to butterflies. This is truly an outstanding garden plant.

This is a compact spiderwort with a long bloom period that is great in rock gardens, flowerbed borders, open woodland gardens, wild gardens, naturalized areas or moist areas along streams or ponds.

General Information +

Botanical: Tradescantia 'Concord Grape'

Common: Spiderwort

Family: Commelinaceae

General Characteristics: This spiderwort hybrid is a compact, clump-forming perennial 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. When the stems of spiderworts are cut, a viscous stem secretion is released which becomes thread-like and silky upon hardening (like a spider's web), hence the common name.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems. Young shoots are susceptible to damage from snails and caterpillars. Spiderwort foliage often sprawls in an unattractive manner by mid-summer. General foliage decline is reportedly less severe with this cultivar, however.

Planting Instructions: Dig a hole large enough to encompass the roots without bending or circling. Set the plant in place so the crown (part of the plant where the root meets the stem) is about 1-2 inches below the soil surface. Cover with soil to the original soil surface and water thoroughly. 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. Foliage usually declines after flowering and should be cut back almost to the ground to encourage new growth and additional late summer to fall bloom. Divide clumps when they become overcrowded.
