Agave 'Nigra'

Agave 'Nigra' – Rare Hybrid with Bold Architectural Form

Agave 'Nigra' is an extraordinary hybrid, believed to originate from a cross between Agave victoriae-reginae and Agave scabra (syn. Agave asperrima), or possibly Agave × ferdinandi-regis × Agave scabra. Highly sought after by collectors, this plant combines the precise geometry of victoriae-reginae with the rugged durability of scabra, creating a rosette so distinctive it is often called the “Sharkskin Agave.” Its architectural silhouette, contrasting colors, and textured leaves make it an ideal statement piece for modern landscapes and high-end succulent collections.

• Leaves: Thick, rigid, and leathery to the touch, deep grey-blue with smooth purple-black margins and a stout, dark terminal spine.
• Surface Texture: Rugged, matte finish, earning the nickname “Sharkskin Agave.”
• Offsets: Surculose (produces pups) for propagation.
• Growth Rate: Slow-growing; takes several years to reach maturity.

Flowering and Lifecycle

• Bloom Nature: Monocarpic – blooms once after decades of growth, then the main rosette dies.
• Flower Stalk: Very tall, often several meters, bearing greenish to yellow flowers.
• Propagation: Plant produces offsets before and after flowering to continue the lineage.

Climate and Hardiness

• USDA Zones: 9 – 11.
