About

Agave colorata is a slow-growing evergreen succulent that develops a rigid rosette composed of broad green leaves covered with a dusty blue-grey coating. The leaves feature undulating edges with sharp serrations and have brown spines at their tips, often displaying patterns of bud imprints. When mature, this plant can send up a tall flowering spike adorned with yellow-orange blooms that emerge from reddish buds. Following the blooming period, the central rosette will die, making way for new offsets that grow at 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.
