The Story

Plant Bio

A large, robust, solitary agave forming a dense rosette of broad, stiff, gray-green to blue-green leaves. Each leaf is armed with prominent, sharp, reddish-brown teeth along the margins and a formidable terminal spine.

Notable for its large, architectural form and considerable cold hardiness for a plant of its size. It is a monocarpic species, meaning it flowers only once at the end of its long life, producing a spectacular tall flower spike.

Uses & Benefits:

Ornamental UsesStriking architectural form adds visual interest to xeriscapes and modern gardens.
Practical UsesDrought-tolerant, requiring minimal water once established.
Ecological BenefitsProvides habitat for desert-adapted insects and birds.
