Care of the shrub Ceanothus griseus or Carmel ceanothus |
|
The genus Ceanothus, family Rhamnaceae, includes more than 50 species of shrubs and small trees native to Central and North America. Some species are: Ceanothus griseus, Ceanothus arboreus, Ceanothus americanus, Ceanothus thyrsiflorus, Ceanothus delilianus, Ceanothus coeruleus, Ceanothus rigidus, Ceanothus papillosus. Common names: Carmel ceanothus, Carmel creeper. This species is native to California. They are fast-growing, compact evergreen shrubs that reach 1 meter (3.28 feet) in height and 3 meters (9.84 feet) in width. The thick, glossy leaves are dark green. The scented flowers appear in highly decorative clusters of blue, white or pink. They bloom in spring and summer. They are used to form bushy groups, as isolated specimens, to cover slopes and in flowerbeds. They are ideal for Mediterranean coastal gardens. Ceanothus griseus grows in full sun and semi-shade exposures; they prefer a south or west orientation. They resist occasional frosts. The soil can be a mixture of normal garden soil with 1/3 coarse sand and a little organic matter. Planting is done in early spring. Water moderately waiting for the substrate to be completely dry. They resist drought well. Fertilize with organic matter and mineral fertilizer in early spring. Prune after flowering to maintain a compact appearance and eliminate wilted flowers. They can suffer Chlorosis if the soil is very calcareous. Overwatering causes fungal attacks. They are propagated by semi-woody cuttings in summer and by woody cuttings in fall. |
