Dark Knight Bluebeard
The 'Dark Knight' Bluebeard is a standout perennial shrub celebrated for boasting the deepest blue flowers among all Bluebeard varieties. It features a tidy, upright growth habit, producing a profusion of flowering spikes late in the summer when garden color is often scarce. This reliable performer flowers heavily each year and serves as a fantastic nectar source for bees and butterflies. Its modest size makes it highly versatile for smaller yards, suitable for planting near low walls, as a hedge, or grouped around larger plants. Ensure planting occurs in well-drained soil, avoiding heavy, wet clay.
