The upright bushy mound of green foliage is almost as much a reason to grow these wild flowers as the large bright-pink hooded blooms. They blossom in the late summer and are best in a moist or wet site recieving something less that full sun (though they are often reported to tolerant of a wide range of considerations). They are native to a large swath of states from Michigan and Wisconsin down the central part of the country and through the Appalachians to the mid Atlantic states.
Grow them in large swathes at the edge of a pond or in a bog garden. Cut them for flower arranging. Plant them to attract butterflies and hummingbirds.
