Carmel Ceanothus (Ceanothus griseus 'var. horizontalis') - Description
C. griseus horizontalis bears glossy, oval, 2 inch, bright green leaves with light blue 1 inch flower clusters.
Carmel Ceanothus (Ceanothus griseus 'var. horizontalis') - Blooming
Typically Wild Lilacs bloom in the spring, but certain species may vary. The flowers range in color from white to all shades of blue.
Carmel Ceanothus (Ceanothus griseus 'var. horizontalis') - Growth
Deciduous and evergreen shrubs. Some are small trees. Plants vary greatly in growth habits. Some grow low, prostrate and spreading, while others are compact and bushy. Grows best in full sun. Trained against a wall, Ceanothus can reach twice the height they would normally grow in an open site. Low growing, prostrate species, like C. americanus, grow well as groundcovers or in large rock gardens. In general, California Lilacs grow best in shrub borders or against sunny walls.
Carmel Ceanothus (Ceanothus griseus 'var. horizontalis') - Planting
Sow seeds in a seedbed, or in containers in fall. Species will hybridize freely. Can also propagate from semi-ripe cuttings for evergreen species, and greenwood cuttings for deciduous species during the summer. Greenwood cuttings are taken from shoot-tips of plants, and are harder than softwood cuttings. Semi-ripe cuttings are cuttings taken from semi-mature wood.
Carmel Ceanothus (Ceanothus griseus 'var. horizontalis') - Pest
Deer may be a problem, but Wild Lilacs with smaller leaves tend to be more resistant to herbivory by deer. Aphids and whiteflies can be a problem, but are easily controlled.
Carmel Ceanothus (Ceanothus griseus 'var. horizontalis') - Interesting facts
The seeds of some Ceanothus can stay dormant for centuries until a forest fire triggers germination.
Carmel Ceanothus (Ceanothus griseus 'var. horizontalis') - Soil and irrigation
Wild Lilacs require excellent drainage. These plants evolved growing on rocky slopes. Some species require total dryness during the summer months (especially the coastal ground-cover species), but others need rare summer watering. Prefers rich soil with good drainage. Lime tolerant, but can become chlorotic in shallow, alkaline soils.
