Permalawn combines hardy low maintenance Kentucky Bluegrass, Fine Leaved Perennial Ryegrass and Creeping Red Fescue to give you a seeding mixture that will adapt to both sunny and shady lawns. The Rye will come fast to provide an environment for the Bluegrass and Fescue to grow. The Blue will eventually take over in the sunny areas and the Fescue will dominate the shady places. All three grasses are very similar in blade width, color and texture to ensure that you will grow a fine looking uniform lawn.
