    I've only seen this nice, easy perennial once, in the Natural garden at the Hawk mountain Raptor Sanctuary north of Reading, PA. It has rigid, erect stems and is much branched at the top with long, narrow, toothless leaves about 3 to 6 inches x 1 inch. It bears its white aster flowers in late July into October. It grows at forest edges, meadows, wetland edges, bogs, and swamps from Newfoundland to southern Manitoba down to Louisiana and northern Florida. Sow seed in fall for blooming plants the second year or it can easily be divided or dug up. It slowly spreads by rhizomes to become a small colony. It is a larval host for the caterpillars of the Pearly Crescent and the Harris Checkerspot Butterflies. It is deer resistant. It is sold by some native plant nurseries as Izel in Washington DC and Prairie Moon in southern Minnesota, plus Midwest groundcovers in St Charles, Illinois.
