Description
This large terrestrial bromeliad was once classified as Vriesea imperialis but is now recognized as part of the genus Alcantarea. It can be found growing on rocky slopes in the Serra dos Órgãos in Rio de Janeiro. It can tolerate dry conditions and full sunlight. Considered one of the giants of the genus, "its leathery leaves measuring 6 inches in width and 5 feet in length." It will take up to forty years before producing an imposing red inflorescence that reaches 8 feet, or even ten feet (3 meters) in height. Its tank will hold up to thirty liters of rainwater.
