Alcantarea extensa is a bold and architectural Brazilian bromeliad featuring striking light green leaves with silvery grey banding, creating beautiful contrast in tropical and contemporary garden settings. Growing to 1.5m in height and width, it produces a dramatic flower spike reaching up to 2m tall, adorned with golden yellow blooms that last for months — a true showstopper in any landscape.
Suited to both pot and garden planting, Alcantarea extensa thrives in full sun to semi-shade and is remarkably low maintenance once established. While it takes 4–5 years to reach flowering maturity, the wait is well worth it — making it a rewarding long-term feature plant for tropical gardens, courtyards, and statement container displays.
