About
This evergreen succulent develops a rigid rosette of arching, powdery blue-grey foliage, characterized by sharp marginal teeth and spines at the tips. Growth is gradual, but it can attain a height of up to 2 meters when fully mature. Once established, mature specimens may send up a tall inflorescence bearing yellow flowers, after which the central rosette will die, giving way to new offsets emerging from the base.
About the genus
Agave consists of either perennial or monocarpic succulents that develop rosettes of typically stiff, thick, spiny leaves. The plants produce funnel-shaped flowers in racemes or panicles that often exceed the height of the rosettes.
