Caryopteris incana Proven Winners© ‘Sunny Blue’ is a compact, deciduous shrub grown for its luminous foliage and rich late-season colour. The softly textured leaves emerge with a golden-yellow flush, maturing to bright chartreuse tones that remain vibrant through summer. From late summer into early autumn, clusters of intense blue flowers appear along the stems, creating a striking contrast against the light foliage while providing valuable nectar for bees and other pollinators. With a naturally neat, rounded habit and strong colour performance, it is an excellent choice for sunny borders, gravel gardens, and modern planting schemes where foliage and flower impact are equally important.
