Ceanothus ?Skylark? is a good choice for small gardens. This lush green  compact Ceanothus thyrsiflorus cultivar flowers later than all other ceanothus extending your flower season into early summer. Dark blue flower spikes appear in spring and into summer  and some flowering will occur again in fall. It is slow growing to 3-6 ft tall with 5 foot spread making it ideal for smaller spaces. Plant in full sun on the coast or in part shade inland. Skylark performs best  in heavier clay soils but will tolerate sandier soils if needed.  Ceanothus are favorites of butterflies and pollinators  adding to their landscape value.
