If you have a large expanse of lawn, you could dedicate half of it to meadow.

Soon we are standing at the edge of an expanse of lawn, stretching almost the entire width and length of the garden.

In its place was concrete topped by a thin layer of soil with a broad expanse of lawn.

Out of this obsessive observation, avenues of trees, islands of flowers, expanses of lawn, vegetable beds and wildflower meadows emerged; but only in my mind.
