Gunnera manicata, commonly known as Giant Rhubarb, is a striking architectural perennial prized for its enormous, deeply lobed leaves that create a dramatic, tropical effect in gardens. Native to South America, this moisture-loving plant thrives in damp, rich soils, making it an ideal choice for pond margins, bog gardens, and shaded water features. Its massive, umbrella-like foliage can reach up to 2.5 meters (8 feet) across, providing bold texture and a lush, prehistoric look to the landscape.
In late spring to early summer, Gunnera manicata produces towering, cone-shaped flower spikes covered in tiny reddish-green flowers, adding to its exotic appeal. Hardy and fast-growing, it requires consistently moist soil and benefits from winter protection in colder climates. Perfect for large garden spaces, this dramatic plant creates an unforgettable focal point while offering shelter for wildlife in its dense foliage. With its bold presence and striking size, Giant Rhubarb transforms any wet garden into a lush, green paradise.
