Lithodora 'Heavenly Blue' (Pot Size 14cm) Gromwell sold by Boma Garden Centre

Lithodora diffusa ‘Heavenly Blue’ is one of the most vivid blue-flowering ground cover plants available, producing an abundance of small, star-shaped, gentian-blue flowers that appear to glow against its deep green, slightly hairy foliage. Flowering generously from late spring into early summer, it forms a neat, spreading carpet that softens edges and brings striking colour to the front of borders.Perfect for gravel gardens, alpine beds, and raised planters, this plant thrives in free-draining, acidic soils where its colour intensity is at its best. It works beautifully alongside other acid-loving plants such as heathers, dwarf rhododendrons, and ericas, as well as contrasting elegantly with silver foliage plants like artemisia or low-growing grasses.Its compact habit makes it especially effective cascading over walls or spilling from containers, where the electric blue tones can be appreciated up close. A refined choice for adding a cool, saturated colour note to sunny garden spaces.
