A well-designed garden will add interest throughout many seasons.
While it may be tempting to select perennial plants on a whim, you may wish to reconsider since you are likely to have them in the landscape for several, if not many years. While some considerations in picking perennial plants are aesthetic, such as bloom color or time, others such as hardiness or heat tolerance will dictate the ability of the plant to thrive or survive in its growing conditions. These questions and more are discussed in the following articles about the beginnings of a perennial garden.
