How to Grow

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").
Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

Unlike many rockery plants, Lithodora diffusa requires a well drained, acid soil that is rich in organic matter. Choose a position in full sun.
More Info Feed and water Lithodora plants regularly until they are fully established. After flowering, lightly trim the tips of Lithodora stems to maintain compact bushy growth.
