This is one of the hardiest and most reliable of the Ceanothus  Low Blueblossom  or also known as Creeping Blueblossom  will grow in difficult areas. It is a low growing 1-2 feet x 4-15 feet  evergreen shrub  that is smothered in powder-blue flowers from May to June. Grows best in any reasonably fertile  well-drained soil in full sun  although it will tolerate some shade. It will survive in sand or clay and is fairly drought tolerant  so will be okay in a coastal area. Plant in full sun or light shade on the coast.  In hotter interior areas  protect it from the heat of the afternoon sun by planting it in light shade or in morning sun.  Low Blueblossom is tolerant of most soils  but prefers good drainage. Once established  creeping Blueblossom will survive the summer with no supplemental water  but is tolerant of irrigation.  In hotter areas  an occasional deep watering in summer is beneficial. Little maintenance is needed.  If necessary  prune lightly to maintain a neat compact shape or to control the size. Hardy to 15 degrees F.
