I made my decision - I went with lazy. I have a butterfly garden seed mix in the backyard along one fence, and i've put the new lily and new geranium there - I figger that'll be the assorted garden. I hope that butterfly mix doesn't also mean mondo-powered bee attractor, but I have a feeling it does.
Out front, I've got mixed forget-me-not seeds (mailed as a gift from the vet in memory of my poor kitty) and low-growing wildflower mix, just around the stairs. It's the kind of flowers I like, and if I see some violets or a nice pot of daisies along the way, I can still stick those in with.
Here's hoping there is indeed no more frost.
