Agave bovicornuta Gentry
Cow Horn Agave
Agave bovicornuta is native to mountainous regions in the Mexican states of Chihuahua, Sonora, and Sinaloa.
Agave bovicornuta is an attractive succulent that forms a solitary rosette of yellow-green to pale green leaves attractively edged with sharp reddish to dark brown teeth and ending in a long, stout terminal spine. The rosette grows up to 3 feet (90 cm) tall and 5 feet (1.5 m) in diameter. Leaves are broadly lanceolate or spatulate, broadest in the middle, up to 32 inches (80 cm) long, and 8 inches (20 cm) wide. They are decorated by bud imprints caused by teeth pressing into the flesh of inner leaves before they unfurl. Some marginal teeth recur back toward the base, and others towards the tip.
When the rosette matures, which usually takes 12 years or more, it produces a branched, up to 23feet (7 m) tall inflorescence with short side branches that bear terminal clusters of yellowish-green, up to 2 inches (5 cm) long flowers. The inflorescence begins to emerge in fall, grows slowly over the winter, and matures during the spring.
USDA hardiness zone 8b to 11b: from 15 °F (−9.4 °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. 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 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 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. When repot, refresh the spent soil with a new potting mix and ensure the plant is firmly anchored in its pot. However, be careful not to pot the Agave too deep, as that will encourage stem rot during the growing season.
