Nipomo Mesa Ceanothus
Ceanothus impressus var. nipomensis
  
About Nipomo Mesa Ceanothus (Ceanothus impressus var. nipomensis) 2 Nurseries Carry This Plant Ceanothus impressus var. nipomoensis is a variety of flowering shrub in the Rhamnaceae (buckthorn) family known by the common name Nipomo Mesa Ceanothus. It is one of two recognized varieties of the species C. impressus. This variety is endemic to the coast of Santa Barbara and San Luis Obispo counties where it can be found on coastal slopes and mesas. It is thickly branched with dark brown twigs and stem. The evergreen leaves are about 2 centimeters long and oval shaped, highly ridged and wrinkled and curling under along the edges. They may be gland-dotted and have grayish hairy undersides. The shrub flowers abundantly in clusters of small blue flowers. The fruit is a crested spherical capsule about 4 millimeters wide.

This is a great Ceanothus to grow in its natural range. Significant amounts of summer water will kill this plant. It needs the cool coastal climate and strong marine influence to make it through the hot season, so don't try to grow it south of Ventura County or inland areas. Prefers sun or part shade and sandy soils. Makes a great hedge.
