Dry Shade

 Ribes sanguineum March 2010

Gaultheria shallon August 2008

Heuchera americana 'Dale's Strain' May 2009

It can be difficult to find plants for Seattle gardens that will grow well in dry shade. Most shade plants prefer moisture. Plants that tolerate dry shade often grow better in part sun. Most of the plants listed below do better in light or partial shade than in deep shade.  Shade can be lightened by pruning the lower branches off overhanging trees.  It is always wise to plan for dry shade to limit supplemental water use. But it is more realistic to water sparingly during summer, than to expect shade plants to do entirely without water. Many of the plants listed below are Washington native plants.  Gaultheria shallon, Mahonia repens & Vaccinium ovatum are Washington native shrubs that do well in dry shade with no supplemental water. Helleborus x hybridus, Maianthemum dilatatum & Polystichum munitum are plants that grow well in shade with little supplemental water.
