Agave utahensis is a succulent plant that forms compact rosettes of stiff, blue-green leaves with spiny margins and a long, light gray to ivory-white terminal spine. The rosettes can grow up to 2 feet (60 cm) tall and up to 3.3 feet (1 m) in diameter, either solitary or offset sparingly from the base. The leaves are lance-shaped and can reach up to 20 inches (50 cm) long and 2.2 inches (5.5 cm) wide.
The flowers are yellow, urn-shaped, and appear in clusters on a spake that can grow up to 12 feet (4 m) tall. The fruits are capsules that are up to 1.2 inches (3 cm) long and contain black seeds.
USDA hardiness zones 6a to 10b: from -10 °F (−23.3 °C) to 40 °F (+4.4 °C).
How to Grow and Care
Agave is not a difficult plant to grow. They're slow-growing and dramatic and will even thrive on a bit of neglect. If you're the type of person who likes to fuss with houseplants and water a lot, Agave is probably not the plant for you. On the other hand, if you're 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 injure small children and even pets.
In general, Agaves do not need to be repotted every year. Most species commonly found in cultivation grow very slowly and take a long time to outgrow their pot. It's also best to handle your Agave as little as possible since they do not like to be disturbed.
