Sedums are a good late flowering plant for the garden. They attract both bees and butterflies. The clump in the front garden has been rather swamped by the Asters but it's still going strong. The varieties grown in gardens are generally cultivated from S. telephium or S. spectabile, not sure what this one is.

 I was surprised to read that S. telephium is native to the UK. I can't recall ever having seen it growing wild so I would be intrigued to find it in a natural habitat.
