Masses of broadly funnel-shaped, purplish-blue flowers cover this evergreen shrub in mid- and late spring, putting on a really impressive display. The foliage is small and grey-green, and when bruised gently it is aromatic. It forms a compact low mound that makes it particularly good for patio pots, larger rock gardens, or front of border positions.
Garden care: Avoid planting too deeply and apply a generous mulch of leaf mould around the base of the plant each spring.
