Description and Cultural Plant Tips

This is a mounding shrub that ranges from 3 to 5 foot tall and has glossy green leaves and inch long medium blue flowers. It is a very fast grower and is considered one of the best ground covers for Marin's coastal areas. It looks great on hillsides and is good for erosion control, Also good for naturalizing and planting enmasse. However, if you have deer this is not the groundcover for you.

Plant slightly above ground in well-drained soil. Needs no fertilzers or amendments. Add compost to clay soils to improve drainage. Plant in full sun in coastal Marin and with light afternoon shade in the hotter areas of Marin. Can be pruned after blooming to control size. Needs little to no water once established.

Ceanothus can get aphids and whiteflies. See the UC IPM for treatment choices. It can also develop root rot if watered too much in summer or if planted in poorly drained soils.
