Long description: Despite its name the Giant Rhubar is not related to the eatable rhubarb as we know it. This impressive plant should be planted in a moist soil (preferably near a lake, canal or pond). The leaves of this strange plant can grow up to 1,5 meters big! A huge antenna-like spike with purpulish-brown flowers will be formed from the center of the plant. In winter the plants dies back to the ground. The foliage of the plant, which has fallen down on the ground, will then serve as protection against frost. The decomposing leaves will eventually enrich the soil again. Early spring the new growth of the Gunnera will start again. A similar species is Gunnera manicata. This variety is known to grow even bigger then the tinctoria; up to 2,5-3 meters big!
