"One of the reasons liatris are such popular cut flowers is their unusual mode of blooming. Unlike most plants they bloom from the top of their flower spikes down to the bottom. You can actually cut a portion off the top of the spike to bring indoors, and the remaining flower heads will continue to open and provide color for the landscape."

"The abundance of fragrant flower produced by the liatris attracts a variety of wildlife all season. The summer blooms attract hummingbirds, butterflies and bees. In the fall, the liatris produces a seed pod (if the blooms are left intact on the plant) that attracts a wide array of hungry birds looking for a meal."
