'Queen of the Prairie' is essentially a taller pink American alternative for our native meadowsweet with, under suitably moist conditions, erect stems up to 2.5m topped by fluffy heads of deep-pink flowers ageing paler from mid to late summer. The foliage is pinnate but with the terminal leaflet palmately lobed - quite handsome! Tolerant of most decent soils if never too dry and very happy in a bog.
