Southern Gardening: Salvia varieties create colorful, informal feel
Many gardeners try to give their landscape the feel of an informal cottage garden. This garden concept has a loose, flowing feel, kind of like you just let plants grow wherever they happen to pop up in the landscape.
I had a professor way back in college who had a unique cottage garden planting method: He would walk through the landscape and just toss plants over his shoulder. We planted them where they landed. And you know what? His gardens looked awfully good.
