Chilean rhubarb

Chilean Rhubarb (Gunnera tinctoria) was introduced from South America and looks like ordinary garden rhubarb but on a larger scale. This ‘rhubarb on steroids’ was often planted in gardens for its interesting form.

But it turned into such a problem plant that in 2008 it was banned from sale, propagation and distribution in New Zealand.

We don’t know of any Chilean rhubarb in the Park, but we know it is present on private land on the western margins, such as at East Wainui, so there is a need to be vigilant—particularly around the stream margins and wetland habitats that it prefers. If you do see any please let us know.
