Description

The Lithodora diffusa Heavenly Blue is a small ground cover with a loose habit, covered with beautiful gentian blue flowers from May to June.

This lovely variety has star-shaped trumpet flowers, with a particularly intense gentian blue color that blooms for several weeks. Its semi-evergreen, villous foliage is a beautiful dark green. Lithodora Heavenly Blue is the perfect companion for heathers as it has similar requirements, but it also thrives in poor and well-drained soils in partially shaded areas or in the sun, alongside field of plants such as linaria, botanical tulips or creeping wormwood.
