Growing Wild Blue Indigo

Here are some essential guidelines for successfully growing Wild Blue Indigo:

  2. Planting: Start Wild Blue Indigo from nursery-bought plants or sow seeds directly in the garden. If starting from seeds, scarify or soak them before planting to enhance germination. Plant the seeds or young plants in spring or fall, ensuring they have enough space to establish their root systems.

Deadhead the faded flowers to encourage additional blooming and remove any diseased or damaged foliage. In late fall or early spring, cut back the stems to a few inches above the ground to promote fresh growth.
  5. Propagation: Wild Blue Indigo can be propagated through division or by collecting and planting seeds. Divide the plant every few years in early spring or fall by carefully separating the root ball into smaller clumps and replanting them. Collect seeds from the dried seed pods and sow them directly in the garden or save them for future planting.
