Lithospermum is a choice groundcover or rock garden plant, making an unforgettable display when grown well. Plants form a low, creeping mat of hairy grey-green leaves, studded with sapphire-blue star flowers from late spring through summer. Plants MUST have a well-drained, acidic soil in order to thrive. Heavy clay soils are sure death. In colder regions this will benefit from a light covering of evergreen boughs as soon as the soil is frozen in late fall. Combines well with Heaths and Heathers, since plants have similar requirements. Evergreen where hardy. Not especially vigorous.
