Louis Edmunds Carmel Ceanothus is a mounding shrub ground cover, reaching 3-6 ft. tall by 12-25 ft. wide. It has dark green glossy textured foliage, and produces violet-blue flowers in the springtime. The plant can grow in full sun in coastal sites, and in some sun to part shade in inland sites. In cultivation it is tolerant of clay, alkalinity, sand, wind and heat, and depending on local climate and soil can be tolerant of some irrigation.
Ceanothus thyrsiflorus var. griseus 'Louis Edmunds' is planted as a large scale groundcover where it has room to spread, and for slope stabilization and erosion control.
This cultivar was selected in 1942 by nurseryman Louis L. Edmunds, who later operated the Louis Edmunds Native Plant Nursery in Danville, from a seedling he propagated and selected at Tilden Botanic Garden (Regional Parks Botanic Garden) in the Berkeley Hills. Ceanothus thyrsiflorus var. griseus 'Louis Edmunds' was given an Award of Merit in 1956 by the California Horticultural Society.
