This prostrate, spreading evergreen shrub is smothered with masses of deep azure-blue funnel-shaped flowers over a long period from late spring to early summer. One of our recommended plants, it's perfect for softening the edges of a sunny raised bed or rock garden outcrop with well-drained, humus-rich, acid soil.


  • Garden care:
    Ideal for thriving in a sunny spot with well-drained acidic soil, Glandora 'Heavenly Blue' requires little maintenance other than a light trim after flowering to maintain shape and restrict growth. Shield young plants from direct, scorching sunlight and harsh winds until they establish themselves firmly. Ensure the soil is moderately rich, well-drained, and acidic, preferably sandy, avoiding heavy clay soil or locations prone to waterlogging.
