Very similar to the Chilean Gunnera but from the other side of the continent, Brazilian Gunnera is even larger and more monstrous than its Chilean cousin. Give it plenty of water and a bog-like setting. Some folks even plant a large saucer under their gunnera’s so they can constantly be sitting in standing water. In a rain garden or by the edge of a pond is a great spot for them too. The stems can be peeled and eaten just like the Chilean Gunnera. A truly exceptional and otherworldly plant!
