Although not actually a grass, King Tut Papyrus falls in the category of grass-like plants and behaves similar to grass in the garden. With triangular green stems and pendulous umbels of greenish flower spikelets, papyrus is a showy bog or water garden feature and can be planted out in very moist areas of your garden that do not support other plants. Sometimes called Niles grass or paper reed, papyrus has been used for millennia as a source for paper-like writing material.
