Dreamy, dark blue flowers with a hint of lavender will make this dependable groundcover come alive with luscious color starting in early May and continuing intermittently well into the summer months. Its deep bloom brings out the best in any shaded area and makes a subtle yet superb contrast with its lustrous, deep green foliage that lines up tightly along thin pendulous stems. ‘Dark Blue is a gardeners’ dream for shady, tough areas where it seems nothing wants to grow. ‘Dark Blue’ thrives in these spots and is one of the best plants anywhere to help prevent erosion and hold soil.
