Dark Knight Bluebeard

Dark Knight Bluebeard

Dark Knight Bluebeard (Caryopteris × clandonensis ‘Dark Knight’) is a compact, deciduous flowering shrub known for its rich deep blue to violet-blue flowers and aromatic gray-green foliage. The rounded clusters of flowers appear in late summer and continue into early fall, providing a valuable burst of color when many summer-blooming shrubs and perennials are beginning to fade. The flowers are highly attractive to honey bees, butterflies, and other pollinators.

Its gray-green foliage provides an attractive contrast to the intensely colored blooms and releases a pleasant fragrance when brushed against. The naturally rounded habit makes Dark Knight easy to incorporate into perennial borders and mixed shrub plantings, while its relatively small size makes it useful in tighter spaces where larger flowering shrubs would be too much.

Dark Knight performs best in full sun and well-drained soil. Once established, it tolerates drought and dry conditions, making it a dependable choice for sunny areas where plants need to handle periods of limited moisture. Because it flowers on new growth, the plant can be cut back in late winter or early spring to encourage vigorous new stems and abundant flowering.

Care Instructions:

Planting: Plant in full sun in well-drained soil.
Soil: Prefers loose, well-drained soil and adapts to clay, loam, and sandy soils.
Watering: Water regularly during establishment. Once established, water during prolonged periods of drought.
Fertilizing: Apply a balanced slow-release fertilizer in early spring if needed.
Pruning: Cut the plant back to the ground or to healthy new wood in late winter or early spring. Flowers develop on new growth.
Spacing: Space plants 2–3 feet apart to allow room for mature growth.
Maintenance: Avoid consistently wet soil, which can lead to root or crown problems.

With its intense blue flowers, fragrant foliage, compact form, and excellent pollinator value, Dark Knight Bluebeard is an outstanding choice for adding late-season color to sunny gardens.

Landscape Solutions:

• Performs well in dry areas where regular watering is difficult.
• Adds pollinator value to gardens during the late-season nectar shortage.
