Bromeliads are related to the pineapple family. Their thick, waxy leaves form a bowl shape in the centre for catching rainwater. Some bromeliads can hold several gallons of water and are miniature ecosystems in themselves providing homes for several creatures including frogs and their tadpoles, salamanders, snails, beetles and mosquito larvae. Those that die decompose and furnish the plant with nutrients. These Plants come in a variety of different flower heads, your plant could be a different flower from the plant / plants pictured. Lovely lush foliage.
