Gunnera manicata, known as Brazilian giant-rhubarb[1] or giant rhubarb,[2] is a species of flowering plant in the family Gunneraceae from Brazil.[3][4]

It is a large, clump-forming herbaceous perennial growing to 2.5 m (8 ft) tall by 4 m (13 ft) or more. The leaves of G. manicata grow to an impressive size. Leaves with diameters well in excess of 120 cm (4 ft) are commonplace, with a spread of 3 m × 3 m (10 ft × 10 ft) on a mature plant. The underside of the leaf and the whole stalk have spikes on them. In early summer it bears tiny red-green flowers in conical branched panicles, followed by small, spherical fruit. However, it is primarily cultivated for its massive leaves.[4]

This plant grows best in damp conditions such as near garden ponds, but dislikes winter cold and wet.[5]

Despite the common name "giant rhubarb", this plant is not closely related to true rhubarb. It was named after a Norwegian bishop and naturalist Johan Ernst Gunnerus, who also named and published a description about the basking shark.

It is native to the Serra do Mar mountains of Brazil, where it is used in traditional medicine for sexually transmitted diseases.[6]
