Found colonising a railway embankment in the USA by a retired horticulturalist, this beautiful coneflower has finely quilled ray florets (petals), which surround a rounded, orange-brown cone. Perfect for adding late colour to mixed or herbaceous borders, they also make fine companions to ornamental grasses.
- Garden care: Lift and divide congested colonies in autumn or spring. Support with ring stakes or brushwood well before the flowers appear.
