Plant Highlights

Arctostaphylos rainbowensis is a rare and endangered species of manzanita known by the common name Rainbow Manzanita. It is endemic to California, where it is known only from northern San Diego and southern Riverside Counties in the Peninsular Ranges. Previously called A. peninsularis ssp. peninsularis or considered to be a hybrid between A. glandulosa and A. glauca. It has now been established as its own species. Height varies from 3' to 10'. It grows from a basal burl and exhibits the typical attractive reddish brown bark.

This manzanita thrives in tough conditions, with minimal irrigation needed. It will stand very hot temperatures, light freezes and full sun. It is not picky about soil type, growing in poor soils, so long as they are fairly well-drained.

Rainbow Manzanita has beautiful red bark and an evergreen habit. Upside-down, bell-like flowers are formed in clusters, followed by plump, red-brown fruits. Rainbow Manzanita has a mounding habit, staying about 4' high and spreading to about 4-6' wide.
