Veronica Spicata is an outstanding silver-leaved perennial often grown for the foliage as much as their flowers. With a good compact habit the plants grow to around 40cm (16in) tall and form a mound of silvery grey narrow leaves. In early summer the plant bears short spikes of deep violet blue flowers. Excellent for massing as a groundcover, edging a sunny border or in the rock garden or border, it also does well in containers. Beloved by bees, butterflies and flower arrangers, trim off faded flower spikes in August, clumps may be easily divided in spring or early autumn.
