I used to have blue nigella, blue and purple larkspur, and those big pink shirley poppies, plus some white marguerite daisies that would come up before my lawn really gets going. These would reseed every year, and it was such a feast for the eyes.
Oh, those daisies. I asked on freecycle for some many years back now. This guy brought me a bushel basket and I planted them. They spread so nice that even when they weeren't blooming, they are so thick they crowd out grass and weeds even being mowed over. The last crew I had mowed or whacked practically all of them. I got my other guy back and see I have a nice stand of them.
Down the street there is a grouping of those and a particular common smallish yellow iris which blooms at the same time. That's what I wanted in the first place. I have yellow iris but not as sweet as these. I guess I won't ask if I can have any. The daisies will be nice encircling a huge antique pink rose I rooted. Inside, I see my nodding blue columbine has survived, glad of that.
I won't post a bunch of pictures but I have tons of photos of combinations like you mention in your post.
