A very long blooming species, these have been growing in the spaces that I tend for a few years and have proven to be perfectly winter hardy for the Ottawa and Perth area.
They are a food source for a variety of pollen and nectar feeding insects, including beetles. They aren’t the fastest species to establish but they seem to be very long lived and are slow to spread. They seem to be quite drought tolerant.
Prairie Moon has a profile on them here and the Xerces Society has a profile on them here
