Lithodora diffusa ‘Grace Ward’ (also called blue lithospermum, USDA Zone: 5-9) in the Boraginaceae family is a choice ground-cover or rock garden plant, making an unforgettable display when grown well. Plants form a low, creeping mat of hairy dark-green leaves, studded with sapphire-blue star flowers from late spring through summer.
The Greek lithodora literally means "stone gifts", referring to their preferred rocky habitats. Plants must have a well-drained, acidic soil in order to thrive. Heavy clay soils are sure death. In colder regions this plant will benefit from a light covering of evergreen boughs as soon as the soil is frozen in late Autumn. Combines well with heaths and heathers, since plants have similar requirements. Evergreen where hardy. Not especially vigorous.
