Can anyone identify this plant?
Hi all, we have had this plant in the garden for years but this year it has gone bonkers. These beautiful flowers have been coming and coming now for the last 10 weeks and the plant is still full of buds, it's been amazing but we cannot remember what it is called. My neighbour thinks it is a rudbeckia but we don't think it is as it has flowered for so long. Can anyone identify it please? Thanks, Claire
