plant sale text: Hollow-stem joe-pye-weed is a large and dramatic perennial that is sure to be a focal point in the garden. As this plant reaches maturity, it will become more and more robust, reaching heights of up to 8 feet and widths of more than 5 feet across. This plant works well in the back of a perennial border or in more naturalized areas. Joe-pye-weeds are some of the best native perennials for butterfly gardening. In late summer, the mauve-pink flower heads will attract many species with their abundant nectar. 2017 N.C. Wildflower of the Year.
