What is this plant?

I've been reading your forums for awhile now, and recently decided to give a food forest/forest garden a shot. I started cleaning up the old orchard in my back yard and found this plant, everywhere. My hope is that it is a welcome addition to the system and I won't need to get rid of it. There are lady bugs and bees swarming it, so that is some encouragement to me that i should just let it be. Any help is appreciated. (The plant with the white flowers is the one in question)

it looks like some sort of relative of the daisy.

It looks pretty, the bugs love it, I would just leave it alone.

Thanks!
