Hohokam Agave, Murphey Agave, Murphey's Century Plant
Agave murpheyi is a succulent plant that forms stemless, freely suckering rosettes of light glaucous green to yellow-green leaves with distinct imprinting, small and closely spaced teeth along margins, and a dark brown to grayish spine at the apex. The rosettes grow up to 4 feet (1.2 m) tall and 4.6 feet (1.4 m) in diameter. Leaves are spatulate, up to 2.6 feet (80 cm) long and 4 inches (10 cm) wide. The terminal spine is up to 0.8 inches (2 cm) long.
A mature rosette produces an up to 13.1 feet (4 m) tall stalk with clusters of 12 to 21 erect flowers at the branches. The flowers are pale green-yellow, up to 3 inches (7.5 cm) long, with a very short open tube. Fruits are woody, rounded, and up to 2.8 inches (7 cm) long capsules. It sets no viable seed but produces bulbils on the stalk branches.

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. However, if you are the type of person who likes to set it and forget it, and you have a sunny window, Agave might be 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 species commonly found in cultivation grow slowly and take a long 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, do not pot the Agave too deep to encourage stem rot during the growing season.
