Deep Shade & Moist Soils

Description: If you have a yard with evergreen trees that provide consistent year-round shade, the following plants will do well on your site. If your yard has seasonal shade that deciduous trees furnish during the summer months, these plants will also thrive. The plants in the following list are tolerant of a moist soil due to poor drainage, or proximity to a stream or lake. While developing your planting scheme, keep in mind that in a natural setting with deep shade, the under story shrubs are usually sparse and located in pockets of light or along the edges of the shady area. In contrast, the groundcover layer consisting of ferns and perennials grows thickly in deep shade. Native huckleberries do well in a moist soil, with plenty of organic matter; they do not like heavy clay soils however. Avoid using huckleberries if you have clay soils.
