Evergreen bugloss is a shade-tolerant perennial that produces striking blue flowers in spring and maintains attractive foliage year-round. It prefers moist, humus-rich soil in partial shade, making it ideal beneath trees or in shaded borders. Water regularly during dry spells and divide clumps every few years to maintain vigour.
