Gladegrass was a grass found in the glades and pastures of the Deepwoods. It was similar to silver grass, pasture grass, meadow hay, lakegrass, bladegrass summergrass, briargrass, greatgrass and sugargrass. Gladegrass was often used by banderbears to make their nests. Phineal Glyfphith had flippers made of plaited gladegrass as part of an equipment to help Cade swim underwater like he did.
