Jonathan Green (10322) Black Beauty Ultra Grass Seed – Cool Season Lawn Seed (7 lb) Review
I tested this grass seed blend on a thin and patchy lawn behind my home. I wanted thick grass that could handle cool weather without turning brown too fast. After a few weeks, I saw new green growth fill many empty spots. The lawn looked softer, darker, and much healthier than before.
What stood out to me most was the rich color. Many seed mixes I tried in the past looked light or weak after growth. This blend gave my yard a deep green shade that looked fresh every day. I also liked that the grass stayed strong during chilly mornings and light foot traffic.

My Personal Experience with Grass Seed Blends For Cool-Season Climates
I used this blend during early fall when the weather started to cool down. The timing worked very well for my lawn. I spread the seeds after loosening the soil and adding light fertilizer. Within days, I could already see tiny green shoots coming through.
My yard usually struggles in shaded areas near the fence. This time, the grass filled those spots better than expected. I also noticed the blades looked fuller and stronger compared to older grass types I had planted before. Even after rainy weather, the lawn kept a neat look.
Another thing I enjoyed was the soft feel under my shoes. The lawn became much more pleasant for outdoor time with my family. I spent less time worrying about dry or weak patches. The overall look made the backyard feel cleaner and more alive.
Comparing with Other Brands
I tested a few other cool-season grass seed products before trying this one. Some cheaper blends grew unevenly and left thin spots across my lawn. A few also lost color after the first cold week. This Jonathan Green mix stayed darker and looked more balanced.
Compared to basic contractor seed mixes, this product gave me a softer texture and thicker coverage. I also noticed fewer weeds growing between the new grass. Many low-cost blends contain filler materials, but this mix felt cleaner and more premium during use.
I think Scotts and Pennington both make decent products, but this blend gave my lawn a richer appearance. It also handled cool weather in a smoother way during my testing period. My yard looked more even after mowing, which made a big difference to me.
Recommendation
I would recommend this grass seed blend to homeowners who live in cooler regions and want a fuller lawn. It worked well for repairing thin grass and building a richer yard color. I liked how easy it was to spread and maintain during early growth.
This product is a smart fit for people who enjoy lawn care but do not want a hard project. The grass looked healthy with basic watering and simple upkeep. I also think it works nicely for families who spend time outside because the lawn feels soft and dense.
If your yard struggles during cold seasons, this blend may help improve the look and texture of your grass. My own lawn became greener and more attractive after using it. For me, the results felt worth the extra cost.
