Jonathan Green’s Black Beauty^® Sun & Shade Grass Seed is our best selling Black Beauty® grass seed mixture because it performs exceptionally well in either full sun or partial shade growing conditions. This mix is perfect for overseeding and will fill in bare spots quickly to improve the appearance of an entire lawn. Sun & Shade contains the 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 seed germinates in 7 – 14 days.
