Native Plant Ground Cover as Grass Substitute

My brother- and sister-in-law, who live in Brooklyn, NY recently asked about the best type of grass to grow in front of their brownstone. The area in question is an enclosed bed that receives some shade. The residents would like an attractive, easy-to-maintain area that can handle a little foot traffic.

First, I suggest that they get a soil test to determine what amendments they need to improve growing conditions. Soil test kits are available at the public library. They come with specific instructions. Once the results of the soil test are in, I suggest thinking beyond grass as a ground cover. Grass requires a relatively high level of maintenance, including watering, cutting, and fertilizers to keep it green.

Native plants are a more environmentally friendly choice and have the added benefit of attracting beneficial wildlife, such as butterflies and birds. Once established, Native plants need little care, since they are well-suited to local soil and climate conditions. Following is a list of Native plants for New York City gardens, as listed in the publication: “Gardening With New York City Native Plants.”
