I thought it the best idea to use ophiopogon, in case Yorkshire Water need to come and unblock our drains at some point. Minimal damage. There's a clump of Ajuga at the other side. Or did you mean about the bird bath? 😄@pelly
@bookworm68 it's in a bed with equal parts topsoil, compost and grit. They like a sunny position but are quite slow to get going. There's no pruning needed, just run your fingers through in March and pull any loose dead leaves away. These probably won't reach their full potential 'cos my soil is too alkaline, they prefer it slightly acidic.
