Better than Knockouts
I just want to quickly comment for anyone debating between the 2, I wish I would have found the Osos before I planted so many Knockout bushes. These seem to have more abundant blooms, that hold their shape longer. I also feel like the Oso reds fade less. They still go a pinker shade in super hot weather, but don’t turn faded pink like the Knockouts. They come on a brighter red, I’d say as well. These were the first bushes to bloom out of all that I planted, and have had nonstop flowers ever since. Not just one or two flowers at a time, the entire (still young/small) plants are covered!
