The plantings on one block of a street in Seattle, in the patches of dirt next to the street: as I walk up the street, the first patch has sunflowers (one in bloom). The next has corn. At that point, I went "Iroquois trinity, where are the beans?" The patch after that has squash (or maybe melon) vines in flower, and plants that I think are beans growing up wires around a central pole.
There are then two more patches with squash vines, and today I saw some squash flowers near the sunflower.
(If you're in Seattle, this is on Broadway just north of Jefferson in First Hill, near Swedish Hospital.)
