Agave murpheyi Gibson
Hohokam Agave, Murphey Agave, Murphey's Century Plant
Agave murpheyi is a succulent plant that produces rosettes of leaves in shades of green to blue-green with pale banding. The leaves are up to 2.6 feet (80 cm) long, up to 8 inches (20 cm) wide, may curl slightly toward the center, and develop a red coloration during flowering. They are lined with small straight teeth and tipped with an up to 0.8 inches (2 cm) long spine. Mature rosettes produce up to 13.1 feet (4 m) tall inflorescence with many flowers along the branches. The flowers are up to 3 inches (7.5 cm) long, greenish with purple or brown tips. Fruits are woody, up to 2.8 inches (7 cm) long capsules containing seeds, but these are rarely produced with the flowers aborting before the fruits form.

How to Grow and Care
Agaves are not difficult plants to grow. They are slow-growing and dramatic and will even thrive on a bit of neglect. If you are the type of person who likes to fuss with houseplants and water a lot, Agave is probably not the plant for you. If, however, you are the type of person who likes to set it and forget it, and you have a sunny window, Agave might the way to go. Be aware that some large varieties will eventually outgrow your room (unless you have a large greenhouse), and Agave can be aggressive. They have irritating sap and sometimes very sharp thorns that can cause injuries to small children and even pets.
In general, Agaves do not need to be repotted every year. Most of the species commonly found in cultivation grow very slowly and take a long time to outgrow their pot. It is also best to handle your plant as little as possible since they do not like to be disturbed. When you do repot, refresh the spent soil with a new potting mix and make sure the plant is firmly anchored in its pot. However, be careful not to pot the Agave too deep to encourage stem rot during the growing season.
