It is a perennial plant that can reach large dimensions, 3 meters high and 2 meters wide.

It has large rough and palmated leaves of great size (up to 1,5 meters) and showy greenish purple color.
Its first buds are yellow, unlike garden rhubarb (Rheum rhabarbarum), that its buds have a reddish color.
Leaves of the variety of Atrosanguineum are very characteristic. It is a giant plant with purple leaves.
The inflorescence is the highest part of the plant. It is held by a floral stem that can measure up to 2 meters in height.
