Gunnera manicata is a robust herbaceous perennial known for its expansive clumps of lobed, rounded leaves that have a coarse texture and are supported by spiny stems, reaching widths of 1-2 meters. The plant produces small red-brown flowers arranged in upright panicles that can grow up to 1 meter tall. It is important to note that many specimens sold under this name may actually be the hybrid Gunnera x cryptica. Both Gunnera tinctoria and G. x cryptica are recognized as invasive species and should not be cultivated. In the UK, strict regulations prohibit the planting or encouragement of these species in the wild. They are banned from sale, and those who currently have them should take precautions to prevent their spread and ensure proper disposal. While existing plants do not need to be removed, any surplus material must be either burned on site or taken to a waste processing facility. The regulations do not extend to G. insignis and G. killipiana, although these varieties may not survive in most gardens. For further guidance, refer to the cultivation notes.

Gunnera tinctoria is a robust herbaceous perennial that forms dense clusters. Its large, rounded leaves typically reach lengths of 1 to 2 meters and are characterized by deep lobes and spiny stems. During the summer months, this plant produces cylindrical flower clusters that stand about 50 centimeters tall and measure 10 centimeters in diameter, featuring numerous small red-brown blooms. These are followed by small green fruits tinged with red. Gunnera tinctoria, along with G. x cryptica, is classified as invasive and should not be planted. In the UK, there are strict regulations regarding these species; planting or allowing them to grow in the wild is illegal. Both varieties are banned from sale, and gardeners who currently have them must take precautions to prevent their spread and ensure proper disposal. While existing plants do not need to be removed, any excess material should either be burned on-site or taken to a waste processing facility. These regulations do not apply to G. insignis and G. killipiana, although these varieties are typically not hardy in most gardens. Refer to cultivation guidelines for additional information.
