2021 Plant of the Year, Winner

The 2021 Montine McDaniel Freeman Medal winner is Cephalanthus occidentalis, buttonbush. The Freeman Medal Selection Committee, comprised of outstanding horticulturists from across North America, unanimously chose buttonbush as the 2021 winner in the category of woody plants. Attributes of Cephalanthus occidentalis include its adaptability to soils, its use when planted in groups along stream beds to slow erosion with fibrous roots, the unique beauty of the flowers, its fruit that provides food throughout the winter for 24 species of birds, and its ability to be planted in full sun or part shade. The common name, honey bells, was used by beekeepers who found the shrub to be irresistible to honey bees and, thus, introduced it into production in the colonies in 1735. A pollinator magnet, buttonbush is a food source for swallowtails, monarchs, skippers, Titan sphinx moths, hydrangea sphinx moths, and royal walnut moths.  Native North American bees such as the bumblebees, yellow-faced bees, green sweat bees, and long-horned bees also regularly visit the shrub. Easily maintained to a desired height through pruning, buttonbush is a great addition to gardens across North America. With its fascinating flowers and the insect and butterfly activity that accompany its planting, it is a notable plant for educating children and adults on its unsurpassed values for the environment! USDA Hardiness Zones 5-9 but plants are evident throughout the lower 48 states.
