Its bright chartreuse leaves are splashed with dark green, creating a vibrant display of color and texture throughout the garden. The foliage is most vivid in warm weather and full sun, while cooler winter conditions and heavier shade tend to bring out more green tones.\u003c\/p\u003e\n\u003cp class=\"x12ofw9d\"\u003eThis evergreen shrub typically grows 6–12 inches tall and spreads 3–6 feet wide, forming a dense, prostrate carpet of foliage. In spring, delicate clusters of light blue flowers emerge, adding a soft splash of color to its already eye-catching leaves. With its graceful, spreading growth, Diamond Heights Mountain Lilac is especially effective cascading over walls, filling borders, or covering open ground.\u003c\/p\u003e\n\u003cp class=\"x12ofw9d\"\u003e\u003cstrong\u003eLandscape Uses:\u003c\/strong\u003e An excellent choice for groundcover, bank stabilization, containers, shady borders, and planting along retaining walls. It can also perform well in dry shade beneath established native oaks when site conditions are suitable. Its colorful foliage pairs beautifully with California native plants such as Blue-Eyed Grass and Coffeeberry.\u003c\/p\u003e\n\u003cp class=\"x12ofw9d\"\u003e\u003cstrong\u003eGrowing Notes:\u003c\/strong\u003e Diamond Heights Mountain Lilac prefers well-drained, sandy, or coarse-textured soils. In coastal gardens, plant it in full sun for the brightest foliage. In hotter inland areas, partial shade or filtered light helps protect the plant from intense heat. Once established, it is drought tolerant and requires minimal supplemental irrigation. Remove any stems that develop entirely green leaves to maintain the plant’s attractive variegation. It is also frost hardy to approximately 2°F.\u003c\/p\u003e\n\u003cp class=\"x12ofw9d\"\u003e\u003cstrong\u003ePlant Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"x12ofw9d\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eBotanical Name:\u003c\/strong\u003e \u003cem\u003eCeanothus\u003c\/em\u003e ‘Diamond Heights’\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOlder Botanical Name:\u003c\/strong\u003e \u003cem\u003eCeanothus griseus\u003c\/em\u003e var. \u003cem\u003ehorizontalis\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommon Name:\u003c\/strong\u003e Diamond Heights Mountain Lilac\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlant Type:\u003c\/strong\u003e Shrub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature Height:\u003c\/strong\u003e 6–12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMature Width:\u003c\/strong\u003e 3–6 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Form:\u003c\/strong\u003e Prostrate, spreading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrowth Rate:\u003c\/strong\u003e Moderate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFoliage:\u003c\/strong\u003e Evergreen, chartreuse with dark green variegation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFragrance:\u003c\/strong\u003e Pleasant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlower Color:\u003c\/strong\u003e Light blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlowering Season:\u003c\/strong\u003e Spring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight Requirements:\u003c\/strong\u003e Full sun on the coast; partial shade or filtered light inland\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Needs:\u003c\/strong\u003e Low once established\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecial Uses:\u003c\/strong\u003e Bank stabilization and groundcover\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCold Tolerance:\u003c\/strong\u003e Approximately 2°F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"x12ofw9d\"\u003e\u003cstrong\u003eA Unique California Garden Selection\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"x12ofw9d\"\u003eDiamond Heights Mountain Lilac was discovered by horticulturist Barry Lehrman in 1985 as a naturally occurring foliage sport in a planting of Carmel Creeper in San Francisco’s Diamond Heights neighborhood near Mount Davidson.
