Nothing conjures up the Wild West like the tall saguaro cactus (Carnegiea gigantea) amid the desert landscape. Their ruggedness evokes grit and perhaps a bit of nostalgia for the cowboy and the open range. An aged saguaro can be between 100 and 200 years old and store hundreds of gallons of water. Indeed it takes 15 years to grow a foot tall, and 75 before it puts out its first arm. And the saguaro is the most iconic among the hundreds of species.

Cacti come in many sizes and shapes. Their hardiness makes them great house plants. Their tough skin and need for little water, as well as their singular beauty, make them stand out in an indoor display. During the growing season give them plenty of light, a high-potassium (i.e. 10-30-10) fertilizer once a month and occasional water and they will be happy.
