I understood this form of Rudbeckia to be an annual and grew them from a packet of seeds last year. Perhaps down to the less severe winter, they are growing strongly once again and will be a bonus in a rather challenging corner of the garden, not least because they came as a free gift from Thompson & Morgan! They are named "Chim Chiminee" and with their hairy appearance do remind me just a little of a sweep's brush which I expect is the reason for the name. In both images I have removed the cluttered bg and replaced it in PS.
Forgive my not having looked in of late. The arm problem continues. The weather too has made my photographic efforts very limited, so these 2 images are from Autumn 2011.
