Drought-resistant landscape plants

Some plants can thrive in sunny, dry conditions. Drought tolerate, the plants rely on their substantial moisture-retaining nature to deal with a lack of water. Their leaves may be small to reduce the amount of foliage exposed to the wind or sun rays. When adding plants to a sunny location, layers of mulch or leaf mold helps retain moisture in the ground.
