The Story
Plant Bio
A stemless, clump-forming evergreen perennial with sword-shaped, spine-tipped, flexible green leaves. The leaves often have conspicuous fibrous white threads curling along the margins. In summer, a tall panicle of nodding, bell-shaped, creamy-white flowers rises from the center of the rosette. Distinguished by its flexible, 'flaccid' leaves that bend downwards and the characteristic white, curly filaments along the leaf margins. The flower stalk (scape) can be pubescent (hairy).
