I think you can safely say that this plant is hardy to zone 3a...it even made it through a -60F winter. I started it from seed collected in Michigan and it has survived in my N MN garden (in beds and in wild areas) for 11 years. The only trouble is that it self seeds enthusiastically so to keep the population down I have to deadhead before seed sets. Nice tall plant for full shade, September, tolerates damp.

This plant is a wildflower that lives in the woods by our house. It blooms in September and is very hardy here. Looks great with the goldenrods and rudebeckias that are blooming now. Great butterfly plant!

I have this growing in both my full sun and my semi-shade garden beds here in Zone 6, PA. It does well in both and I haven't had any scorching of leaves at all. Seems to like both areas equally well. A very easy plant to care for, seems to grow in any conditions and deals well with drought. The butterflies love it and it blooms beautifully into October when everything else is dying out.

This is a favorite plant in my fall garden when little else of color is going on. It blooms well into October and produces a mass of flowers reminiscent of cumulus clouds. The flowers make a good complement to a fall bouquet of asters and goldenrod. It is a generous self-seeder in the shade of our tree canopy.
Clump forming perennial from Eastern North America.
Has lance shaped to ovate, toothed, mid green to greyish leaves. Stems are erect dark purple or brown in colour. Bears pure white, fluffy looking flowers.
Flowers August - October
Likes an alkaline, moist, well drained soil in partial shade, hot sun will scorch the leaves quite badly and frosts may kill off young shoots and leaves so a sheltered position is wise.
Has been used in the past for treating fever, liver problems and as a cure for the common cold.
