Ceanothus griseus var. horizontalis 'Diamond Heights' (Diamond Heights Carmel Creeper) - A beautiful, prostrate groundcover that grows to 1 foot tall by 6 feet wide, it features 1 inch oval shaped, lime green leaves with irregular splashes of dark green. The yellowish tones are brightest under sunny, warm weather conditions whereas green predominates in shady sites and during the cooler winter months. Although most notable for its leaf coloration, the pale blue springtime flowers are a frothy bonus. Plants perform best in light shade near the coast and need increasing protection from hot sun when planted further inland to avoid leaf burn. Well drained soil and occasional supplemental irrigation is suggested for the plant to look at its best and is required in inland gardens. Hardy to about 20 F. This plant is slower growing than other cultivars of Carmel Creeper and one should remove any stems with solid green leaves that periodically develop. For those who are attracted to variegated foliage, this unusual low growing Ceanothus selection will definitely appeal. We find it, particularly attractive when used in light shade where it can brighten an area - is a bit too blinding for our tastes when used in a bright sunny location unless this is the effect one is seeking and unless in a coastal garden the foliage will likely burn if grown in full sun. This was a sport selected by Barry Lehrman in 1985 from a planting of Carmel Creeper (Ceanothus griseus var. horizontalis), that was found in the Diamond Heights neighborhood on Mount Davidson, the highest hill in the center of San Francisco. Ceanothus griseus var. horizontalis is now currently thought to be a variety of Ceanothus thyrsiflorus, making the correct name for this plant Ceanothus thyrsiflorus var. griseus 'Diamond Heights' 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 information on this page is based on research about this plant that is conducted in our nursery library, from online sources, as well as from observations made of this plant as it grows in the nursery, in the nursery's garden and in other gardens where we have observed it. We also incorporate comments received from others and welcome getting feedback from those who may have additional information, particularly if this information includes additional cultural tips that would aid others in growing Ceanothus 'Diamond Heights'.
