Its maintenance is low and it is used for ornamental value on road slopes revegetation and landscaping slopes around rural and mountain homes. Description: Buckthorn Family (Rhamnaceae). Ceanothus x flexilis is a native, evergreen, semi-erect shrub that grows 0.6 to 1.2m (2 to 4 feet) high and spreads to 0.6 to 2.4m (2 to 8 feet) wide. It is a naturally occurring hybrid between buckbrush (Ceanothus cuneatus) and squawcarpet (Ceanothus prostrates). The leaves are opposite and the flowering period is April and May. Flower clusters are small with white to bluish, umbellate flowers. Adaptation: Ceanothus x flexilis is adapted to lower elevations that receive a coastal influence. Establishment and Management After Ceanothus x flexilis has formed a third pair of leaves they can be transplanted individually to larger to 1 gallon containers. The young plants will be ready for their permanent location in 11/2 to 2 years. New plants should be watered occasionally until they are well established; after which, deep watering every 1 to 1 months will be adequate to maintain uniform growth. Container plants may be available from local nurseries. Dig a hole two to three times the diameter of the root ball and at least six inches deeper. Backfill the hole with six inches of native soil. Make a few, 1/8 inch deep vertical cuts in the root ball, or carefully 'tease' roots away from the root ball with your hands to encourage roots to grow into the new soil. Set the plant into the hole with 8 feet spacing between each plant and fill in around roots, firming the soil with your hands as you fill until the hole is half full. Fill the hole with water and allow to settle. This will settle the silt and eliminate air pockets around the roots. Backfill with enough planting mix so the plant will set at the same level it was growing in the container. Water to allow soil to settle, then add more soil if necessary. Build a berm of soil to form a watering basin around the outer edge of the hole. Break the basin down after two or three years. Provide the plant with weed control measures during the first year. Seed Production: Ceanothus x flexilis is a hybrid cross and does not produce seed. - USDA NRCS. 1991. Notice of Release of 'Cuesta' Ceanothus x flexilis | 1779245 | CCEA 42 |
