Description

The maritime ceanothus is found in the Arroyo de la Cruz in northern San Luis Obispo County. The habitat is characterized by minimal fluctuations in humidity and temperatures - thanks to the Pacific Ocean - and by frequent high winds. As in many areas of high winds, the affected plants develop compact forms which minimize wind damage. The maritime ceanothus grows to two to four feet, an unusual height for a ceanothus and quite desirable for domestic landscaping. The ‘popcorn’ selection grows to a wide mound to about four feet in height. The leathery leaves are an attractive gray green with holly-like serrations on the margins. ‘Popcorn’ is named for the bright white flowers that appear in round clusters along the branches in mid-winter. Plant this selection in soil of at least medium drainage and provide some protection from the afternoon sun in hot, interior locations.
