Perennials by Height
Perennials come in many sizes from very small to huge. These dependable plants return every year to beautify your landscape. They are useful in the landscape for several reasons. In garden design it pays to have plants return every year without a need of replanting them. For border designs place taller plants in the back and medium in the middle with smaller height plants edging the border, it's a great way to design with perennials by height. Although for a cottage style they can be interspersed haphazardly, but still keeping in mind the tallest should go towards the back. Very tall perennials can be used as a privacy screen blocking unsightly views or neighbors homes. Perennials are so helpful with many re-seeders and runners that continue to grow. You can eventually divide and replant to make many more perennials.
