General Information +

Botanical: Tradescantia virginiana 'Zwanenburg'

Common: Spiderwort or Trinity Flower

Family: Commelinaceae

General Characteristics: Spiderwort is a low-growing and clump-forming. Blue to white, three-petaled flowers (.75-1.5" diameter) accented by fringed yellow stamens open up, a few at a time, each for only one day, from terminal clusters (umbels) containing numerous flower buds. Arching, grass-like, dark green leaves up to 7" long and 1/2" wide are folded lengthwise forming a groove. Sometimes commonly called wild crocus. The flowers bloom from late-spring to mid-summer. Excellent for providing some color in difficult locations, or in naturalized plantings. Easily grown in soils that are moist to boggy. Can be sheared to the ground in midsummer. New foliage and flowers will return with Fall.

Planting/Care Instructions +

Pests or Diseases: No serious insect or disease problems.

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. Grow in average, medium wet, well-drained soil in part shade. Prefers moist, acidic soils. Tolerant of poor soils. Divide clumps when they become overcrowded. Foliage declines after flowering and should then be cut back almost to the ground to encourage new growth and a possible fall bloom. Can self-seed and spread in the garden in ideal growing conditions.
