About Creeping Blueblossom (Ceanothus thyrsiflorus var. thyrsiflorus) 6 Nurseries Carry This Plant Creeping Blueblossom (Ceanothus thyrsiflorus var. thyrsoflorus) is a the low growing form of Ceanothus thyrsiflorus of native tree or shrub that grows in coastal central and northern California, extending from Santa Barbara to near the Oregon border, growing 1- 5 miles from the shore. The other variety of this species, Ceanothus thyrsiflorus var. griseus (Carmel Ceanothus) is more variable in form, extends less into northern california, and sticks more closely to the coast.

Creeping Blueblossom has profuse attractive sky blue flowers and makes a great ground cover. It prefers full sun to part shade in its native cool coastal environment, and part shade to full shade if grown in hotter and drier inland areas. It tolerates occasional light summer water, but is still quite drought tolerant. It grows well in many different soil types, from clay to sand, and tolerates poorly draining and fast draining conditions.

This variety was previously called C. thyrsiflorus var. repens.
