Lithodora diffusa 'Blue Star'
Lithodora diffusa 'Blue Star' is a delightful alpine perennial forming neat, evergreen cushions of compact needle-like foliage. During spring and early summer, it becomes smothered in distinctive star-shaped flowers, each featuring crisp white margins highlighted with vivid blue brushstrokes through the centre of the petals.
Its low-growing, spreading habit makes it an excellent choice for rock gardens, alpine troughs, gravel gardens, and the front of sunny borders. The evergreen foliage provides year-round structure and interest, while the vibrant flowers create a dazzling seasonal display.
Thriving in a sunny position with well-drained soil, this easy-to-grow variety is ideal for adding colour, texture, and ground-covering interest to smaller spaces and specialist alpine plantings.
