Common names: Blueblossom, Blue blossom ceanothus. This species is native to Oregon and California. They are shrubs that reach 6 meters (19.68 feet) in height; The varieties used in gardening (var. repens, for example) only reach 1 meter (3.28 feet) in height. They have small, dark green leaves with rounded tips and serrated edges. They produce showy blue or white inflorescences that are highly decorative. They bloom in spring and can bloom again in fall. They are used to cover dry areas of the garden such as rockeries and slopes; they are also grown in pots. They are recommended for gardens by the sea. Ceanothus thyrsiflorus needs full sun or semi-shade exposure. The ideal soil should be sandy and slightly acidic; they do not tolerate clay or excess water. Always water moderately as they are shrubs that tolerate drought very well. Prune lightly after spring flowering to remove wilted inflorescences. They are plants quite resistant to pests and diseases; they can suffer chlorosis if the soil is very calcareous. They propagate by woody cuttings in autumn or by tender cuttings in early spring. |
