Overview
This epiphytic bromeliad grows as thin, branching, wiry stems covered in tiny silver scales that absorb moisture and nutrients directly from the air rather than from roots or soil. In its native range it drapes from tree branches in humid, frost-free woodland; across the UK and similar temperate climates it is grown as a houseplant or under glass, hung where air can move freely around it. Regular misting or soaking keeps the strands supple, and bright, indirect light brings out its best silvery colour.
