The gap next to the path is where the Rhodanthe was growing. They ran out of steam, possibly due to the dry weather. I have pulled them out.
I haven't grown Fennel before. I bought it for the foliage and I had expected to take off the flowers when they appeared as I thought they were very bright. Now they are flowering I quite like them, and so do the hoverflies.
Belinda at Wild Acre has published her list of favourite flowers for growing and cutting. I shall be making notes.
