Agave ferox (botanically
classified as Agave salmiana var. ferox), also commonly known as
‘ferocious agave’, ‘tame maguey’ or ‘pulque maguey’, is an imposing
perennial succulent plant native to Mexico. It stands out as one of the
largest varieties of agave and is highly prized in xerophytic
landscaping for its sculptural silhouette and great hardiness. It
develops a large, compact basal rosette with no visible stem. A mature
specimen can exceed 1.5 to 2 metres in height and spread to over 3
metres in diameter. The leaves are fleshy, rigid and dark green to
bluish-green in colour. They have strongly undulating edges bearing
black, hook-shaped spines measuring around 3 cm. The apex of each leaf
ends in a very rigid terminal spine that can measure up to 10 cm in
length. Monocarpic flowering: Like other agaves, it flowers only once
in its lifetime when it reaches full maturity (between 10 and 25 years),
after which the rosette dies. It produces a gigantic vertical
inflorescence that can reach a height of 6 to 10 metres, covered in
yellow flowers.
