Gunnera Manicata is an enormous and very striking tropical perennial plant whose leaves alone can reach individual diameters of 9 feet or more. Despite its tropical origins, Gunnera grows well in temperate and sub tropical zones as long as it's provided with plenty of water and given proper winter care. A patch of Gunnera manicata can grow to cover a very large area, so space arrangements should be made. Good soil with steady moisture, by a pond or stream perhaps, and a great deal of space, is all you need to enjoy this magnificent plant. Zone 7+.
