Vivacious herbaceous

I always enjoy a visit to RHS Harlow Carr Gardens when the main herbaceous borders are in full bloom. (This was a few weeks ago.) Some years they are better than others, perhaps due to the weather and/or the choice of planting. There were too many wildly mixed colour combinations for my personal taste this year. I don't tend to like pinks and yellows together... Mind you, I'm a fine one to judge, as I don't have a green finger on my body! Whether they appeal or not, they are certainly a zingy sight.

I did like the colour combination below: a dark pink sedum (?) with attractive burgundy leaves against a vibrant turquoise grass that I've never noticed before.
