Dry Shade

It can be difficult to find plants 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.

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 & Vaccinium ovatum are 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.
