Title: Plants to stabilize sandy slope in Massachusetts
Answered by: Nan Hampton
QUESTION:
Dear Mr. Smartypants, I am working on a small public housing project in Chelmsford, MA, northwest of Boston. We have a steep, sunny and SANDY slope and I am stumped as to what to recommend that will stabilize the slope and be attractive as well. The slope is between 3:1 and 2:1. Many thanks.ANSWER:
Grasses are a good place to start because their fibrous root system holds the soil effectively. Here are some that grow in Middlesex County in sand and sun:
Carex blanda (Eastern woodland sedge) is not technically a grass, but closely related. This one is evergreen.
Carex pensylvanica (Pennsylvania sedge) is another sedge that should work well.
Elymus canadensis (Canada wild rye)
Eragrostis spectabilis (Purple lovegrass)
Panicum virgatum (Switchgrass)
Schizachyrium scoparium (Little bluestem)
Sorghastrum nutans (Indiangrass)
Sporobolus cryptandrus (Sand dropseed) and here are photos and more information.
A combination of some of the grasses above, mixing those of various heights and textures, with some of the following shrublike plants to give color and variety should be an attractive solution to your problem.
Artemisia frigida (Prairie sagewort)
Artemisia ludoviciana (Louisiana artemisia)
Achillea millefolium (Common yarrow)
