Rock Garden

The Rock Garden was installed in 2006 to complete the re-design of the viewing mound. It provides a showcase for low growing plant material appropriate for the northwest garden, including colorful perennials, alpines and dwarf and miniature conifers and shrubs. The focus is on plants less than 3 feet tall at maturity. The garden is built at a scale to demonstrate a project that could be installed by the home gardener. Rock is from a local source and does not exceed two–man size. The garden beds were created using 6 to 12 inches of sharp builder’s sand on top of the native soil. The garden needs little water in the summer. Good drainage is essential to the garden’s success since the plants in this type of garden require deep root systems in order to thrive. The Rock Garden was partially funded by a grant from the North American Rock Garden Society and designed and installed by Evergreen Arboretum and Garden Foundation volunteers.
