Portea petropolitana, commonly known as Gravata, is an evergreen perennial herb native to the Atlantic Forest biome of Southeast Brazil, particularly thriving in the understory of coastal forests. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters). This bromeliad has a rosette of stiff, spiny leaves and produces striking flower spikes with bracts that range from red to violet, and small flowers that are often blue or purple, blooming in the summer. The flowers are quite showy and can add a tropical flair to gardens.

Gravata is valued for its exotic appearance and vibrant flower spikes, making it a popular choice for ornamental use in subtropical and tropical gardens. It can be used as an accent plant, in containers, or as part of a mixed border. In cultivation, it requires well-draining soil, consistent moisture, and can tolerate a range of light conditions from part shade to full sun. While it is relatively low maintenance, it is sensitive to cold temperatures and should be protected from frost. It is not known to have significant disease problems, but overwatering can lead to root rot.CC BY-SA 4.0
