Jonathan Green Black Beauty Sun & Shade Grass Seed performs exceptionally well in either full sun or partial shade growing conditions. This mix is perfect for over-seeding and will fill in bare spots quickly to improve the appearance of an entire lawn. Sun & Shade contains four families of cool-season turfgrasses: turf-type tall fescues, Kentucky bluegrass, perennial ryegrass and fine fescue, making this our most versatile grass seed mixture. This 15 lb bag of grass seed is a mix of black beauty grass seed, which is perfect for high traffic areas, and sun and shade grass seed, which is perfect for lawns that get both sun and shade.
