Aster

Asters are easy to grow perennial plants that take care of themselves all summer long. Their vigorous blooms appear later in the season, right when other flowers begin to fade. A surefire way of adding great fall color for years to come, Asters' gorgeous flowers will stay true and strong until hard frosts set in. Aster is a popular and dependable food source for Monarch butterflies, who rely on the nectar of late-season blooms to fuel their fall migration.
