About
Agave horrida is a perennial succulent that develops a rosette reaching up to 1 meter in height, characterized by its rigid, dark green foliage. The leaves are edged with dark brown teeth and spines that gradually turn a pale greyish-white. Upon reaching maturity, this plant may send up a slender floral spike adorned with yellow or occasionally purple blooms, following which the rosette will perish.
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.
