Lithodora diffusa 'Heavenly Blue'
Bright royal blue, star shaped blooms smother mats of narrow, evergreen foliage throughout late spring and summer. With such a long flowering period, Lithodora ‘Heavenly Blue’ gives a superb performance as ground cover in rockeries, troughs or at the edge of borders. This hardy, low growing shrub is easy to grow and holds an RHS AGM. Height: 15cm (6"). Spread: 60cm (24").
