Description and Cultural Plant Tips

The Carmel Creeper Ceanothus is a dense, dark green groundcover with 1 inch long light blue flowers. It looks good cascading over walls or berms, on hillsides for erosion control and can also be used as a tall replacement for grass. Deer like to munch on this plant but will not kill it. If you have a deer problem look for a small leafed variety such as C. 'Joyce Coulter'.

Plant slight above grade in well-drained soil. This Ceanothus does okay in heavy clay soils but it is best to add compost to provide better drainage. Needs no amendments or fertilizers. It requires little to no water in summer and will live longer with less summer water. Benefits from light pruning after plant flowers.

Enjoyed by bees and beneficial insects. It is also a treat for deer.

Although quite resistant to diseases and pests, Ceanothus can be attached by aphids & whitefly but these are easy to control.  Can develop root rot from water molds if watered to much in the summer or if drainage is poor.

Master Gardener Comments

I have this Ceanothus cascading over a wall and it looks lovely in the spring. The bright green foliage looks good all the time. It does get nibbled by deer. Do not water in summer for a longer life.
