Shrubs for Shade
For many species of plants, moderate to dense shade inhibits proper growth; for others, it is a definite requirement. Unless you’ve already studied the sun path across your property, the first thing you’ll need to do is document the number of hours for which each area receives full sun. Make note of the spots that never get any, as well as those where dappled sunlight (considered light shade) is the heaviest.
Look at what already grows in these areas. If some plants have not performed well in the past, consider moving them to an area with more sun exposure. When a mature tree of 30 feet is fully leafed out, its shade-producing capabilities can extend much farther than you might think.
Always choose shrubs that are suitable and proven in your hardiness zone. Shade-loving species usually also want plenty of moisture and cool temperatures, yet some of the hardiest shrubs will also tolerate sun. Other species will not be able to compete for water and nutrition with the root systems of large trees.
Lastly, remember to consider the long-term size of the shrub you want to plant. Choose a spot where it can reach full size without crowding or interfering with the light requirements of nearby plants.
