Long description: Puya bertoriana can be distinguished through its curving leaves. It forms dense rosettes of gracefully arching, narrow, dark bluish-green leaves with the underside densely white scaled. As all Puyas, bertoriana forms an amazing flower spike. The antenna-like spike is filled with uniquely collored exceptional metallic, shimmering, deep dark greenish-blue flowers. Given a very well-drained, sheltered position, bertoriana is almost fully hardy!
