Trumpet Creeper (Campsis radicans) shot Tuesday in the Fitler Square area. It's funny how the truck reverse beeping starts up while I'm backing up. #Bloomstrolling

The frustrating thing about the Navy Yard is knowing there are great finds that you just can't get to. Sometimes you can even see them, but it's just like nondescript yellow flowers that are probably Smooth Beggarticks but I can't get past that fence to get decent shots.

Eastern Baccharis (Baccharis halimifolia) shot yesterday at the Navy Yard. I'd never seen this in the Navy Yard before, but it is relatively common along the southern tip of South Philly as well as in John Heinz, so it is not surprising at all.

I was able to get some better shots of these flowers yesterday & was able to use the Rhoads & Block key to confirm that they are Smooth Beggarticks (Bidens laevis). The other flowers in this shot are Frost Asters (Symphyotrichum pilosum), which are common in the area. #Bloomscrolling

It shouldn't be surprising that Saltmarsh #Goldenrod (Solidago sempervirens) is one of the only plants thriving where they piled salt. Shot yesterday off Columbus Boulevard.

I believe that this is Smooth Beggarticks (Bidens laevis) but let me know if you think otherwise. Plant id is hard from a distance. Shot yesterday in the Navy Yard. #Bloomscrolling #Wildflowers #Wallflowers #Flowers

I only found one and it wasn't particularly showy for the species, but I did find what I was primarily looking for in the Navy Yard today, Purple Loosestrife (Lythrum salicaria). #Bloomscrolling #Wallflowers #Wildflowers

This #Sunflower was knocked down over a month ago and is still alive and kicking. That's a tough plant.
