Puya berteroana


Perennials

Growing into a spectacular evergreen foliage clump up to 10 ft. across, this Chilean native is crowded with narrow, sharp-tipped, swordlike gray-green leaves to 2 ft. long; edges are sharply spined. Develops flower stalks that resemble giant asparagus spears; they reach 4–6 ft. tall during spring bloom, when they bear massive clusters of 2-in.-wide, bell-shaped blossoms in metallic blue-green and steely turquoise, accented with vivid orange anthers. Spiky branchlet ends protrude from flower clusters. Use in large rock gardens or in big containers. Tolerates poor soil. Often mislabeled as P. alpestris.
