Wildflower from the central United States. Unlike other more upright ironweeds I've grown, this one grows into a rounded mound of thread-leaved foliage, which is covered in purple flowers in late summer.
We left this plant behind in our Pennsylvania garden (and wish it well); we don't grow it in Houston.
