Title: Ground cover for shaded sandy soil in Long Island, NY
Answered by: Barbara Medford

QUESTION:

I live on the north fork of Long Island (Zone 7) I would like to find a grass or low ground cover that will grow in shaded sandy soil. The yard has quite a few trees. It also has to stand up to moderate foot traffic.

ANSWER:

The best we can do is go looking in our Native Plant Database for low growing plants native to New York that will tolerate shade. In terms of foot traffic, we would suggest paths or walkways with a layer of shredded hardwood mulch under your trees. It has to be replaced from time to time, but helps keep the ground and tree roots warm (or cool), holds in moisture, and can be walked on freely. As it decomposes, it continues to improve the texture of the soil beneath it, and is attractive.

We found several low-growing, blooming perennial plants, some of them evergreen. We also thought you might be interested in some native grasses, not very tall, that will do well in a shady condition, hold their place year-round, and are easy to care for. Again, they can't be walked on, but might serve as a border.
