Mixed blooms

As previously noted, back in the spring or thereabouts I hastily planted a couple of little packs of seedlings, labeled only as mixed zinnias. You don't have to be a deeply experienced gardener to have learned that "mixed" in this context can mean anything from "our own uniquely tasteful blend" to "color unknown", and to suspect that spindly little seedlings in an inexpensive pack fall into the latter category.
As it turns out, the seedlings from the first pack, planted behind the house, are all a vivid hot pink bordering on magenta--except for one white one. The ones from the second pack, planted in front, have been paler--a weak pink, white, a faded salmony orange--except for the most recent one, which is taller and hot pink like the ones in back, and attracted a hummingbird this afternoon.
We have had at least two hummingbirds in and out of the yard lately, sometimes arcing towards each other as they fly upward. I don't know if this is some sort of territorial challenge, or courtship, or play.
