English trough containers are stone-like garden containers you can make at home from common materials. They are great for shallow-rooted hardy perennials, dwarf alpines, herbs or annuals. Examples of these versatile troughs can be seen in the English Walled Garden and Heritage Garden.
Nancy Clifton teaches trough-making and other garden workshops through the Joseph Regenstein, Jr. School of the Chicago Botanic Garden. Look for her classes online and in the catalogs. For registration information, visit www.chicagobotanic.org/school.
