This project studied water use of three types of plants—woody, herbaceous perennial, turf—from three types of landscapes—Mesic, Mixed, Xeric.
Irrigation was applied for optimum landscape quality over two years and water use was measured using a water balance approach.
For woody plants and herbaceous perennials, we found that under well-watered conditions, canopy cover rather than plant type or water use classification was the key determinant of water use.
