Ceanothus griseus var. horizontalis (Carmel Creeper) - A fast growing groundcover to 2 1/2 feet tall by 15 feet wide with 2 inch long oval, glossy green leaves and light blue flower clusters that appear winter through spring. Leaves are larger and usually lighter green than the similar Ceanothus griseus horizontalis 'Yankee Point'.
Best grown in coastal conditions; needs summer watering and partial shade inland. Hardy to about 20 degrees F. Grows taller if planted too close together or allowed to mound on other plants. In the book Ceanothus by Dave Fross and Dieter Wilken all plants previously designated as Ceanothus griseus are now considered to be Ceanothus thyrsiflorus var. griseus but we will continue to list it under the older name until this new name gets more widely accepted.
The genus name comes from the Greek word keanthos which was used to describe a type of thistle and meaning a "thorny plant" or "spiny plant" and first used by Linnaeus in 1753 to describe New Jersey Tea, Ceanothus americanus. The specific epithet means "glorious" or "superb".
The information displayed on this page about Ceanothus griseus var. horizontalis is based on our research conducted about this plant from books in our nursery library as well as from information that is provided by reliable online resources.
