Plant details

Gunnera is one of the biggest and most spectacular, architectural, herbaceous plants, commonly thought of as 'giant rhubarb'. The plants need a lot of space because it is difficult to restrict their size. They look best as specimen plants in a damp bog garden, or beside a large pond where the reflections reveal the prickly undersides of the leaves. The fat growth buds clustered in the crown are prone to frost damage, so pile the dead leaves and stems into a mound over the plants in autumn for winter protection - they make quite a feature of their own. The Royal Horticultural Society has given it its prestigious Award of Garden Merit.
