With a few notable exceptions (like prickly pear and the S1 plant I keep mentioning), there isn’t much blooming now in the Potomac Gorge. In the past week I’ve see a few long-leaved summer bluets and Venus’ pride, various Erigerons, and this: hairy skullcap (Scutellaria elliptica, Lamiaceae).
It’s one of nine species of skullcaps known in the Maryland piedmont, and the only one I see regularly. Look for it in dry, rocky woodland areas. This one was right along the towpath, and it may be the most perfectly-formed inflorescence I’ve ever seen on this species.
