Totally unlike the tall veronicas with spiky flowers, 'Waterperry Blue' is a low-growing, long-flowering groundcover. It was discovered by the Waterperry School of Horticulture in England.
During the cooler months, this selection sports glossy, deep green leaves that are flushed with burgundy and copper overtones that intensify as the temperature drops. In areas with mild winters, this colorful foliage will persist through the winter. From mid-spring through summer, however, the foliage is a mat of pure green.
This lush foliage is an excellent backdrop for the multitude of lavender-blue flowers with white eyes. From mid to late spring, it forms a tranquil carpet of blue that expands to naturalize as far as it is allowed. This initial show is followed by continuous waves of blooms for weeks at a time from summer to fall. Butterflies gather to drink their sweet nectar.
'Waterperry Blue' makes an excellent groundcover or alpine plant for the rock garden. It is also great at softening the hard edges of stone paths and walls.
