Agave xylonacantha is a succulent plant that forms a usually solitary rosette of thick fleshy triangular leaves with light grey irregularly-shaped spines along the margins and a long terminal spine. The rosette grows up to 1 foot (30 cm) tall and 6 feet (1.8 m) in diameter. Leaves are up to 3 feet (90 cm) long and 4 inches (10 cm) wide. They vary in color from yellow-green, silver-green, and blue-green to olive-green and have a lighter center stripe. Flowers are greenish to pale yellow and appear on an erect, unbranched, up to 11 feet (3.3 m) tall flower spike in spring.
