Ceanothus Concha

An RHS Award of Garden Merit selection, Ceanothus ‘Concha’ is a vigorous, evergreen California lilac forming a dense, arching shrub with small, glossy dark-green leaves and abundant deep blue flower clusters in late spring to early summer. In Ireland it performs best in full sun and a sheltered position, in fertile, well-drained soil; ideal as a free-standing shrub or trained against a warm wall. Prune lightly after flowering to maintain shape, avoiding cuts into old woody growth.

To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images.

Rate of Growth: Moderate to fast
