Home Life in Idyllwild Summer holly unique to southwest Life in Idyllwild Summer holly unique to southwest By Halie Wilson - September 13, 2011 8755 0 Facebook Twitter Google+ Comarostaphylis diversifolia is a species of shrub in the heath family known by the common name “Summer holly.” Native to Southern California and Northern Baja California’s coastal chaparral habitat, it grows slowly to 12 inches tall and 8 feet wide or slightly larger. This shrub needs good drainage and indirect water if planted out of its range. It resembles a manzanita with berries similar to those on a madrone tree or a funny looking toyon. The fall fruit is a bright red, juicy drupe with a bumpy skin. It is hardy to 10 degrees Fahrenheit or slightly lower.
