Billbergia nutans (Queen's-Tears) is an epiphytic bromeliad native to Brazil, Paraguay, Uruguay, and Argentina. This plant is often used as an ornamental plant, and it is probably one of the most common bromeliads grown. It is a durable house plant because this bromeliad can often withstand several periods of neglect. Being epiphytic, bromeliads can grow almost anywhere - on the side of a tree or planted in the ground. They have few roots, just enough to anchor them, and they get their moisture and nutrients from the air like the name suggests. They like humidity and, when it rains, their cups fill with water.
