A new and distinct cultivar of Ajuga plant named ‘BINSUGPLU’ which exhibits a compact mat-forming habit comprised of short internodes and contrasting foliage as between the deep pink to purple color of the newly emerged leaves and the gray-green color of the mature leaves. In addition, the leaves of ‘BINSUGPLU’ are rounded and thick, and exhibit a slight pewter-like metallic sheen. In combination, these traits set ‘BINSUGPLU’ apart from all other existing varieties of Ajuga known to the inventor.
