Liatris aspera Michx, the Rough Blazing Star, has a widespread distribution from Michigan to the Carolinas and on westwards as far as Texas. The sessile, globose flower heads are arranged in a loose spike. It is best identified by the concave phyllaries getting their purple tips long before the flowers open. At it's north-western limits it meets Liatris ligulistylis and forms intermediates. Pictures by Martin Bohnet.
