Lithodora diffusa 'Heavenly Blue' is a low-growing evergreen groundcover admired for its intense cobalt-blue star-shaped flowers that appear in late spring and continue through summer. The plant forms a dense mat of small, slightly hairy gray-green leaves, creating a striking carpet of color when in bloom. Prefers light shade and moist, well-drained acidic soil.
