My wife’s favourite flower is the Rudbeckia. Well, certainly for autumn though I’ll punt for the dahlia. It cannot be denied that the burst of beaming yellow dominates the border in September and October. They look sensational. The photographs were taken on 31st August at RHS Harlow Carr from their trial of varieties grown from seed. They intend to leave them to see how many of the annuals survive the winter. Sadly I note that Thompson and Morgan have sold out of their mixed seed. Chiltern Seeds have their own mix however.
