Jonathan Green Black Beauty Sunny Grass Seed contains turfgrass varieties that perform best in full sun growing conditions due to their ability to tolerate heat and have great drought resistance. These Black Beauty turf-type tall fescues possess a waxy leaf coating, like the skin on an apple, which preserves moisture by limiting evaporation and shielding the grass leaves from turf disease. This product performs particularly well on slopes where water runs off and in lawns with a southern exposure, whereas regular grass seed mixtures succumb to heat and drought stress.
