Agave shawii is a species of monocarpic succulent plant in the genus Agave, commonly known as Shaw's agave. It is a rosette-forming plant characterized by glossy, green leaves with toothed margins. After several years of slow growth, the plant puts all of its resources to produce a towering stalk of flowers, and then dies. The death of the flowering rosette is compensated by the growth of numerous clonal pups. This species is segregated into two subspecies, one native to the coast of southwestern California and northwestern Baja California, known commonly as the coast agave, and another native to the Baja California Desert, known as the Goldman agave.

Agave atrovirens, called maguey verde grande is a type of century plant native to Oaxaca, Pueblo and Veracruz states in Mexico. It is the largest of all the Agaves, occasionally reaching a weight of two long tons. Each succulent leaf can be up to 14 feet 9 inches in length and weigh one hundred pounds (45 kg) apiece. In the variety A. a. cochlearis these leaves can also be up to 16 inches (41 cm) wide. As in other Agaves the leaves form a rosette, from the center of which, after many years, a panicle of flowers emerges on a long scape or peduncle which at first looks like a vast stalk of asparagus, but later grows to more than forty feet in height, develops side branches near the top and numerous flowers which open red and gradually turn yellow. Agave salmiana, the species with the tallest inflorescences, is frequently lumped with A. atrovirens as the varieties A. a. salmiana or A. a. sigmatophylla. If this is valid, then A. atrovirens also has the tallest inflorescences of any Agave, and of any known plant. Each rosette flowers and fruits once, then dies. According to Fayaz this is one of the species which makes offsets or "pups". A. atrovirens is one of the pulque agaves used in the production of mezcal.
