I have a pretty big backyard with a small raised flower bed by my patio, I'd like to put flowers in it, I want something that will come back every year. Also right now the sides of the bed are pretty bad I'm planning on putting a new side what should I use, it's rocks right now.. Any ideas for my new yard would be greatly appreciated. I'd also like to put a swing or bench, I have two toddlers!! I need something strong. Lol. Anything else I should include in my yard??
