I have 1100 sq. Ft. Hill garden in front of my house. I am going for a purple/ coral domination broken up with some whites. SO, I planted early and late bloomers hoping to extend the color interest. Orange Reprise, In a Flash, Eleanore Roosevelt etc, with mid season Backdraft in purple/ peach bit one inbetween. Wish me luck..... as I read your great design thoughts, I am reminded of the " bonus" plants that come with our orders. Love the surprise, but then where to put them? I may start a small bed just for them!
