This is a lovely gardenplant and seldom seen overhere in Netherlands. It's droughtresistant, likes sun and has a very long bloomingperiod...looking nice in all stages... even with spent flowers. I hope it 's a perennial overhere.
If not...I 'm sure I 'll sow it again.

American Indians used the leaves and stems to make a tea to treat a variety of ailments,two of which were stomachaches and headaches. The Cheyennes used a solution made by boiling the leaves and stems to treat rattlesnake bites and relieve poison ivy, also.
very durable perennial. original plants are 13 years old now (from seed) and continue to perform like clockwork. I have two colors, a solid yellow and a rust/yellow mix. I think they are both columnifera based on the foliage although I am not certain. blooms all summer long. mixes very well with miscanthus and hemerocallis
