Sandpaper Vervain (Verbena scabra)Observer
nativeplantaddictDescription
Came back to take better photos of this plant. It is only this plant in this spot, I didn't see a colony. The leaves are rough. I checked Floraquest for the northeast to help with ID and this plant resembles this species. Normally found further south it seems.

Genus BaccharisObserver
lillybyrdDescription
I found several populations of this Baccharis that is not identifiable- it’s not any of our FL native species.
All plants across the region are less than 2ft tall, and have fleshy leaves. Occurring in coastal salt marsh, co-occurring with B. angustifolius, B. glomeruliflora, and B. halimifolia - all of which exhibit their typical height and characteristics.
Not sure if this is undescribed, or a species not know to occur in FL which isn’t representatives in our floristic keys.

Shrubby St. John's-Wort (Hypericum prolificum)Observer
nativeplantaddictDescription
Was able to remove some mother plants and a lot of smaller plants. Temporarily in my yard until they're relocated. NJ conservation got back to me and a land steward I know is picking some up. And rest to whoever wants them.
This was a cool spot, going to miss it! The silver lining is these plants seem very hardy. There were many young plants around a mother so they seem to reseed easily. There was a dense thicket of these that I didn't see the last few times I came here. These were growing in clay and another wild type in the same county I saw was growing in more sandy soil. They were growing in full sun and part shade. Was also able to make a few cuttings from some over the summer, all of them took and they root easily.
I understand the demand for warehouses, but it was hard to watch.

wernerehlDescription
Thanks to@margaretcurtin for ID assist. Spikelets densely pubescent, leaf blade is also but with pubescence less than a millimeter long, (for this metric, ignore the longer stiff straight hairs on the leaf margin) and the plant is fully prostrate and in very sandy open habitat almost on the ocean shore. This is a state watch-listed species and known from only Southern New England.

Susquehana Sandcherry (Prunus susquehanae)Observer
ciafreDescription
Photos 2-4 are comparison of P. susquehanae (left) with Aronia melanocarpa (right), with which it frequently intermingles and superficially resembles from afar. Note the presence of glands, absence of black dots on the midvein, and red petiole on the Prunus. The Prunus also tends to have whiter undersides (see third photo).
