Nidularium is a genus of terrestrial or epiphytic bromeliads that produce rosettes of spiny-edged leaves; in the center of the plant, brilliant, red, bract-like leaves form a smaller rosette-like nest–thus the common name bird’s nest plants.
Nidularium has dense, spreading, prickly-margined leaves that form a basal rosette that collects water. When the plant is about to flower, the base of the leaves near the center of the rosette turns color, usually rose-red to dark red.
Flowers are surrounded by colorful bracts that grow in small clusters near the center of the plant. Nidularium may bloom at any time of year.
Nidularium is a genus of 45 species native to rainforests in Brazil.
