Broomsedge (Andropogon virginicus – with two racemes per peduncle and concealing bracts) is fruiting on the Reading Viaduct. Prairie three-awn (Aristida oligantha – with three very long awns) is in fruit. Solidago rugosa is flowering. All are very common up there.
This afternoon, a Red Admiral, a few Blue-winged Wasps (Scolia dubia), and honeybees were at the blooms of a patch of Allium in the physic garden in the Pine Street yard of Pennsylvania Hospital.
On the north side of Tower Street, at Pensdale Street, in the scrub there, an individual of Solidago gigantea (it has 3-nerved leaves, and its lower stem is somewhat glaucous and smooth, and the top of the stem, at the inflorescence, is hairy – also, it is losing its lower leaves) is flowering (with a terminal inflorescence).
Solidago flexicaulis is flowering in the yard of the Friends Center on Cherry Street, just west of 15th Street.
The goldenrod (most likely Solidago rugosa) growing on the embankment of the Reading Viaduct, alongside the railroad tracks that lead to Market East (i.e., the east side of the embankment), aren’t blooming yet.
Solidago rugosa is flowering along the old railroad embankment (west side) running south from Erie Avenue, just east of B St.
Kyllinga is flowering on Hermit Lane, just off of Henry Avenue, by the side of the road.
