General Description

Identification, growth habits, culture and ornamental use of landscape and indoor plants adapted to climates of California, with emphasis on the need for sustainability and water wise plants. Plants emphasized will come from current cloud-based resources. Covers those plants best observed and studied in the fall of the year. Plant materials from local regions will also be included. Laboratory required.
