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". 

This information about Ceanothus griseus var. horizontalis displayed on this web page is based on research we have conducted in our horticultural library and from reliable online resources. We also will relate observations we have made about it as it grows in our nursery gardens and other gardens visited, as well how our crops have performed in containers in the nursery field. Where appropriate, we will also incorporate comments that we receive from others and we welcome hearing from anyone with additional information, particularly if they can share cultural information that would aid others in growing this plant.
