Alcantarea regina

A large rosette bromeliad that grows on bare granite and gneiss outcrops in the coastal mountains of Rio de Janeiro and São Paulo states. It forms broad rosettes of wide leaves and sends up a tall branched inflorescence with fragrant, night-opening flowers. In cultivation it wants full sun, warmth and a fast-draining mix.
