Overview
Gunnera chilensis is a garden plant in the genus Gunnera, part of the Gunneraceae family. It is native to southern Chile and Argentina.
About
Gunnera chilensis is a clump-forming perennial in the family Gunneraceae from southern Chile and Argentina, notable for very large palmate leaves and tall flowering panicles. The plant produces flowers in the UK from June to August. Stems bear numerous coarse projections and the species has been grown as an ornamental outside its native range. It has a history of spreading from garden sites in some countries, so size and placement should be considered before planting.

In the garden
Gunnera chilensis is a perennial member of the Gunnera genus native to southern Chile and Argentina. It is characterised by very large, deeply divided leaves and erect panicles of flowers; in the UK its flowering period is June to August. Although not closely related to culinary rhubarb, it has a similar overall appearance and has been introduced to gardens beyond its native range. When siting Gunnera chilensis, allow plenty of room for its clump to develop and for the tall inflorescences. Plants are typically grown as a bold architectural element where their scale can be accommodated; when grown in constrained beds they can overwhelm neighbouring perennials and shrubs. The species has been recorded spreading from cultivated plantings in some parts of the world, so gardeners should monitor seed set and manage discarded material to limit escape from the garden. In the UK context, Gunnera chilensis is best used where its size is an asset rather than a liability: large borders, waterside margins and areas set aside for major structural plants. Given its capacity to naturalise beyond planted sites, choose a location that suits long-term containment rather than frequent relocation.
