Agave parrasana, commonly known as Cabbage Head Agave, is an evergreen succulent native to the high-altitude, semi-arid regions of Northeast Mexico. It forms a dense, symmetrical rosette of fleshy, thorn-tipped, blue-green leaves that can reach up to 60 cm in height and width. The leaves are adorned with contrasting red thorns, adding to its ornamental appeal. Mature plants may produce a dramatic flower spike up to 6 meters tall, with flowers that open red and turn yellow, signaling the end of the rosette’s life cycle. However, the plant can propagate through offsets.

Cabbage Head Agave is valued for its architectural form and is often used in xeriscaping, rock gardens, and as a focal point in drought-tolerant landscapes. It is hardy to −12 °C (10 °F), making it suitable for outdoor cultivation in sheltered environments. It has earned the Royal Horticultural Society’s Award of Garden Merit, indicating its excellence for garden use. This agave prefers full sun exposure and thrives in well-draining soils, requiring minimal water once established. It is suitable for USDA hardiness zones 7–10. Gardeners should be aware of potential issues such as scale insects and chlorosis due to magnesium deficiency. To prevent these problems, maintain proper soil conditions and monitor for pests.CC BY-SA 4.0
