Agave titanota Gentry
Chalk Agave, Rancho Tambor Agave
Agave titanota is a succulent plant that forms a usually solitary rosette of thick, ghostly white to whitish-green leaves with irregular teeth along margins. The rosette can grow up to 2 feet (60 cm) tall and occasionally produce offsets near the base. The leaves are narrower toward the base, broadest near the tip, and can reach 2 feet (60 cm) in length and 5 inches (12.5 cm) in width.
The mature rosette sends up a tall flowers stalk with yellow flowers. The rosette dies after flowering.
Agave titanota is native to Mexico. The typical form described by Howard Scott Gentry in "Agaves of North America" originates from seeds collected at or near the type locality at Rancho Tambor in Oaxaca, where it grows on limestone cliffs and ledges.
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °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. If, however, 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 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 long to outgrow their pot. It's also best to handle your Agave as little as possible since they dislike being disturbed. When repot, refresh the spent soil with a new potting mix and make sure the plant is firmly anchored in its pot.
