  • circleLife cycle

    Tradescantia 'Concord Grape', also known as spiderwort, begins its life cycle as a seed, germinating in moist soil in spring with temperatures ranging from 65 to 75 degrees Fahrenheit. The seedlings emerge and develop into young plants with narrow, lance-shaped leaves and begin to form clumps. As the plant matures, it produces distinctive, three-petaled grape-purple flowers which bloom from late spring to early summer. Throughout the growing season, the plant continues to produce new foliage and blooms in favorable conditions. In the fall, growth slows and the plant begins to die back with the onset of cooler temperatures and frost. The plant enters dormancy in winter, storing energy in its roots to regrow the following spring, thus completing its perennial life cycle.

      Spring to Summer

    • Propogation: The most popular method of propagating the Tradescantia 'Concord Grape', also known as Spiderwort, is through division. This is typically done in the spring or early summer when the plant's growth is most active. To propagate by division, you would gently lift the plant from the ground, using a spade or fork, and then tease apart the clumps into smaller sections, ensuring that each section has a good amount of roots and shoots. These divisions can then be replanted immediately into moist soil, spaced about 8 to 12 inches apart to allow sufficient room for growth. Water the new plants generously after planting to help establish them. This simple vegetative method maintains the genetic consistency of the plant and ensures new plants will be true to the parent's form and coloration.
