From Flora of Indiana (1940) by Charles C. Deam
Infrequent to frequent except in the northern counties, where it is rare or absent. This is a woodland species found principally in dry soil along streams. It is a coarse perennial usually turning black on drying and soon beginning to disintegrate so that specimens more than twenty years old become very brittle. The largest plant I have seen was 7 feet high, and another large plant was 6 feet high with a lower side branch 4 feet long.
