Which ground cover is commonly used for drought-resistant landscapes?

Native grass is commonly used for drought-resistant landscapes due to its ability to thrive in arid conditions with minimal water requirements. These grasses are well-adapted to local climates and soil types, making them an ideal choice for sustainable landscaping. They typically feature extensive root systems that help them absorb moisture efficiently and withstand dry periods. Using native grass can also promote biodiversity, as it often supports local wildlife and requires less maintenance compared to other plant types.

In contrast, thorny bushes, while they may have some drought-resistant varieties, generally do not provide the same level of hardiness or adaptability as native grasses. Petunias and roses, although beautiful and popular in many gardens, require more water and care, making them less suitable for a drought-resistant landscape. They are typically dependent on a regular supply of water to maintain their health and floral displays. This makes native grass the clear choice for creating landscapes that are both aesthetically pleasing and environmentally sustainable in the face of drought conditions.
