Viburnum tinus can be used as a hedge and can be kept to the required
size. But the roots could be a problem in that situation. I suppose
you could point out to him, in a friendly spirit, that if there's
damage to the wall, he'll have to be the one that repairs it. I'm not
sure where you are but if the soil is sufficiently well-drained and the
position sunny enough etc. he could grow lavender more successfully in
terms of size and colour, or depending on location, rosemary. I can't
imagine why anyone would want to get rid of Muscari, myself! But
Cerastium tomentosum (aka Snow In Summer) would probably do well and
it's pretty rampant. It also has a long flowering season. And how about
looking at Erigeron karvinskianus.

I think ordinary lavenda is a bit too big unless you are thinking of
Munstead which is a nice idea, but I don't know how long it lives for.
Doesn't it need hot summers to really do well? I'd cetainly put that on my
list. Erigeron is ok if you are into daisies, not for me but maybe my
neighbour might prefer them.Cerastium's a nice idea perhaps as a possible
alternative to Iberis Sempervirens which I'm a big fan of, and it flowers
non stop for nearly 3 months into early summer. Armeria Splendens is another
one when it comes to summer flowering.
