Perennials for Dry Shade

What is dry shade?

Dry shade describes areas under shade trees where tree roots compete for water. These are areas that receive very little water.

Some other examples of where there is dry shade are:

  1.  Areas North or East of buildings where overhangs, wind patterns or obstructions reduce expected rainfall.
  2.  Northern facing slopes
  3.  Areas where soil amendment is difficult. Example: under maple and pine trees.

The following is a list of perennials for this difficult to landscape area of the garden. Note that some of these plants will tolerate dry shade, but do not expect lush growth or appearance; some will also flower more sparingly. Some of these perennials will need regular watering until they establish themselves. Many of these perennials will become drought tolerant usually in  two year’s time.

Before planting, the addition of compost to these areas will improve the soil’s moisture holding ability. If pockets of tree roots are involved, compost should be added to the planting hole before planting perennials. Likewise, these plants may need more frequent applications of a low nitrogen fertilizer since they are in competition with the trees for nutrients . The addition of a light layer of mulch (1-2 inches) will also aid in the survivability of these plants in dry shade. Care should be taken not to mulch or apply topsoil over the tree roots as this interferes with the water/O2/CO2 transpiration from the tree to the air and vice versa. Mulch applied directly next to the tree trunks will also eventually compromise the life of the tree.

This fact sheet was researched and written by Master Gardener Christine M. Banigan ‘01

Thanks to you Christine for allowing me to place your fact sheet on my web site. Christine is from Long Island which is also a zone 7 area as we are in New Mexico. Some of the plants she lists may not grow equally well in New Mexico because of differences in soil pH and other factors. There are also differences in common names and some of the ones listed here printed in italics are names that we use here.
