Get rid of the muscari. They are a weed...ok a beautiful weed....and take over very easily.
Easier said than done I guess. My garden was full of muscari. I propagated them with zeal, loving that blue colour. Then I realised my folly and remove every one I can.
They will spoil your houseleeks Berkeley. They will simply multiply and dominate. Can you clear one or two houseleeks? Dig up and remove the bulbs as you see them? How big an area are we talking about? Perhaps start at the top and clear them there?
You should be able to lift houseleeks and replant intact.
If you can't face it right now perhaps at summer's end? The bulbs will still be visible
