Perennial shrubs return each year as bigger and brighter plants for the landscape. Some clever gardener decided to place a perennial shrub into a container. The result led to the frequent use of shrubs in commercial and home landscape design. Container-grown shrubs require the same care as garden-grown shrubs. The one caveat lies in protecting the plant's roots during colder months of the year. Air circulation around the pot makes container-grown perennial shrubs susceptible to freezing.
