Ceanothus thyrsiflorus var. repens (Creeping Blue Blossom) is a low-growing, evergreen shrub noted for its abundant clusters of fluffy sky blue flowers in mid spring to early summer. The flowers are so profuse that they literally cover the shrub, transforming the plant in an explosion of blue. The blooms are borne on horizontal arching branches clad with shining dark green leaves. Attractive to birds and butterflies, Creeping Blue Blossom makes an excellent evergreen groundcover. It is also useful on banks and slopes or in the foreground in mixed borders.
