You might also consider Anthemis punctata ssp. cupaniana.

That one slipped my attention.

I was in the plant sales area of a garden yesterday, and they had both
Anthemis punctata ssp. cupaniana and Leucanthemum hosmariense (yet
another name for Rhodanthemum hosmariense) on sale; but I couldn't tell
them apart. Perhaps they're more distinguishable at full size.
