Despite the scary name, this is a lovely wildflower native to our Eastern meadows that draws butterflies and birds. One especially showy variety, E. maculatum
'Gateway,' has wine-red stems 5 to 7 feet tall, topped by dusky rose nosegays a foot across. Use as a tall anchor in a perennial bed or as a temporary screen, since stems die back to the ground in winter.
Requires full sun; average to abundant water. Grows as a perennial in zones 4-8
