About
Agave gentryi is a perennial succulent that develops a rosette of wide, rigid, inward-curving green leaves. The leaf margins are lined with prominent teeth and feature red-brown spines at their tips. This species has a slow growth rate, ultimately achieving a height of around 2 meters when fully mature. Once established, mature specimens may send up an elongated, branching flower spike adorned with yellow-green blossoms. Following the flowering phase, the central rosette will die, but new offsets will emerge from the base to continue the growth cycle.
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.

Care notes
- Cultivation
- Grow under glass in cactus compost, water freely when in growth, but keep almost dry over winter. Apply a dilute, liquid fertiliser 3 or 4 times during the growing season. Can be moved to a sunny spot outdoors in summer, but ideally needs to overwinter in a greenhouse or conservatory; may tolerate lower temperatures if kept completely dry.
