Ironweed (Vernonia spp.)
I don’t remember off-hand which Vernonia this is, probably the common native one ~ angustifolia, perhaps, but it’s robust, and self-sows quite readily.
It’s lovely in the garden from mid-August through September; butterflies and bees love it. It’s all over the pocket meadow in front - original plants and self-sowed ones.
They’ll definitely be edited a bit more when we return from our last foreign Home Exchange this year.
In the meantime, I hope our simultaneous Home Exchange partner for the month enjoys the Tiger Swallowtails that are visiting currently. Not to mention the hummingbirds on the Salvia guaranitica along the side of our parking space/driveway.
