I have a large area in the middle of my front yard that I want to cover with plants, cottage style. Its an odd shape that is about 22' wide at the base and tapers to about 10' wide. The length is about 21'. I've attached a picture showing the area on our property survey.

Would it look bad to just fill the area with my favorite "cottage-y" plants? Should I try to break up the space? If so, how? All advice is welcome!
