One of the many cultivars of Leucanthemum × superbum, aka Shasta Daisy. To get one you like I'd visit a nursery and choose one in flower.

Not sure we can get very specific about cultivar :-) There are quite a number of dwarf or very compact Shasta daisies (Leucanthemum x superbum) on the market - Tinkerbelle, Little Princess, Snowcap, Snow Lady, LIttle MIss Muffet, Whoops-a-Daisy, Snowbound........

All around 15 inches or less.

Thanks. That’s all i really needed to find something nice.
