The Best Perennials for the Shade
For many gardeners, shady locations can be a huge challenge. Finding perennials that do well in in the shade can be difficult at times, but once the correct balance of plants is found, the payoff for a garden in the shade is a wonderful woodland retreat right in your back yard.
Preparation for Planting Perennials in the Shade
Since perennial plants will continue to grow year after year, selecting the correct plants for the shade garden is essential. Begin by assessing the light in your shady area, so the correct plants can be selected.
- Partial Shade: Areas that are in partial shade will receive 3–6 hours of sunlight daily.
- Full Shade: A full shade location in the garden will get less than 3 hours of sunlight daily.
Adding organic matter such as peat moss or compost is also essential in a shady area. Most shade gardens are located under trees. Although the tree makes a beautiful backdrop for your garden, the tree’s roots will compete for the water and nutrients your perennials need to thrive. By adding organic matter you are adding needed nutrients to the ground and helping to make the soil drainage more efficient.
The perennials listed below will give you a good starting point of proven winners in a shade garden.
Asters flower in late summer or fall when little else is in bloom in the shade garden. Because of their height, they look best when planted in the back of the garden.
