Community Q&A. Papyrus plant belong to the genus Cyperus. This tall, robust, leafless aquatic plant can grow 4 to 5 m (13 to 16 ft) high. It forms a grass-like clump of triangular green stems that rise up from thick, woody rhizomes. The stems are rigid and triangular and have white pith inside.
According to the USDA, Ground turkey lasts 3-4 months in the freezer. However, I have noticed that the flavor changes in about half that time (and I'm talking about unopened store-bought ground turkey). If you want it to last longer, use packaging that is designed for freezer storage.  See Related Links.
I may be incorrect, but when I do it I just give an estimate. Usually I buy my ground turkey in a 1 pound package, since there are 16 ounces in a pound I would eat about a 1/4 of the meat and assume I was having 4 oz. It may not be a perfect science but it seems to be working so far.
