This half-acre backyard garden is the result of the owner's 40 years of experimentation with a wide variety of desert plants to test their tolerance of the region's climatic extremes (hot summers, cold winters and average annual precipitation of only around 6 inches). Twenty raised beds contain about 300 varieties of cacti and other succulents. A greenhouse displays exotic succulents from around the world. Peak bloom is from May into July.
