Lithodora diffusa 'Heavenly Blue': A Sky-Blue Carpet for Rock Gardens

Lithodora diffusa 'Heavenly Blue' – Heavenly Blue Lithodora

Few ground covers rival the intense, true-blue blossoms of Lithodora diffusa 'Heavenly Blue'. This low-growing, evergreen perennial forms a dense mat of narrow, dark-green leaves that become completely smothered in tiny, star-shaped, gentian-blue flowers from late spring into summer. Perfect for rock gardens, slopes, and the front of sunny borders, 'Heavenly Blue' brings a cool, alpine aesthetic to any landscape.

Native to the Mediterranean region, Lithodora demands sharp drainage and thrives in full sun to light shade. It dislikes wet feet, especially in winter, so gritty, sandy soil is ideal. Once established, it is drought-tolerant and requires little maintenance beyond occasional shearing after flowering to maintain a compact habit. Its vivid blooms are a magnet for bees and butterflies, adding ecological value to its ornamental appeal.
