There are many wonderful drought-tolerant plants available for our southern Idaho gardens. Some of the plants included here are native to Idaho, while others are not. All are commercially available, sun-loving and easily grown. For more suggestions on waterwise landscaping choices, visit the Idaho Botanical Garden at 2355 Old Penitentiary Road in Boise or the Idaho Native Plant Society online at www.idahonativeplants.org. Sulfur buckwheat (Eriogonum umbellatum), shown here, grows in every Western state. It is tremendously variable in terms of flower color, leaf shape and size. ANN DEBOLT
