Hi Djwest, if you look for seed of Bellis perennis, this is the common daisy, here in the UK we spend a lot of time trying to eradicate it from our lawns.
There are some cultivars available, but in my experience they all revert to type eventually, and are best grown as a biennial, and whatever you do, do not let them set seed, or you will never be rid of them, Derek.

I love them in my lawn and the more the merrier! Hope they like your area Dj.
