Drought-tolerant plants include yarrow, purple coneflower, tall bearded iris, rosemary, thyme, sage, lavender and blanket flower. Succulents can also be suitable plants for dry climates.
Yarrow can tolerate both drought and heat. At the same time, it is a hardy plant that can survive in temperatures as low as -40 degrees Fahrenheit. The blooming plant grows high, which makes it a good addition to cut flower arrangements. It requires full sun and blooms from mid-summer until early fall.
The purple coneflower is a variety of Echinacea. It has pinkish-purple flowers that thrive in sunlight. It is a hardy plant that does well in both dry and cold conditions.
The tall bearded iris is very easy to grow. It prefers full sun and requires well-drained soil to thrive. When it grows in the right conditions, it can reach heights of up to 27 inches.
Many woody herbs do well in dry climates. Rosemary, sage, thyme and lavender can all tolerate drought conditions. However, they require sun and warmer climates to survive. Although thyme can tolerate temperatures as low as -30 degrees Fahrenheit, lavender and sage can only survive in temperatures above -20 degrees Fahrenheit and Rosemary dies down if the thermometer drops below 10 degrees.
Succulent plants make good additions to gardens in dry climates. Options include Hen and chicks, sedums and sempervivums.
