I planted all 12 of the magenta periwinkles (that looks very weird, doesn't it?) around the boxwood in front of the building. The soil is full of earthworms, enough so that I carried one over to the next tree [1]. By the time I was done my knees were stiff: the low railing around the tree left me more-or-less crouching as I dug and planted.
It looks good, though, and if they take that's the job done more or less indefinitely: periwinkles are perennials, spread, and in fact generally used as groundcover. I might tuck something else between them, while they're still new and haven't spread.
If the farmer I spoke to Saturday comes through, I'll get proper darker-purple periwinkles at least for the tree I moved the worm to. Or maybe I'll just pick up a flat of marigolds tomorrow.
[1] These are Manhattan sidewalk trees, each with an island of earth around it, and then sidewalk.
