Alcantarea imperialis 'Rubra' is a spectacular large-form bromeliad featuring a bold rosette of deep maroon-red flushed leaves that command attention in any tropical or subtropical garden. The intensity of its rich red colouring varies beautifully from plant to plant and deepens with increased sunlight exposure, making each specimen uniquely striking. When it flowers, the spike can reach an impressive 5m tall and the bloom can last up to a year — a truly unforgettable garden event.
Suited to large pots indoors and out, Alcantarea imperialis 'Rubra' thrives in warm, humid conditions with free-draining soil and enjoys sunny to shaded positions. Care is straightforward — fill the centre cup with rainwater, fertilise lightly in spring, and enjoy. After flowering, pups emerge at the base and can be separated and grown on, giving you more plants to enjoy for years to come.
