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.

Q:Do rudbeckias respond well to Chelsea chop?Asked on 10/23/2013 by paintmegreen from London
The Chelsea chop is normally carried out towards the end of May, to limit the size, and control the flowering season of many herbaceous plants. I haven't heard of Rudbeckias being given the Chelsea chop, -I wouldnt think there would be much of the plant to chop at that time of year being a late flowerer.
