I have seen some Skullcaps before, but I don't really yet know this plant. Looks like a nice perennial of the Mint Family for part-shade and shady locations. Native from Iowa to New Jersey and south in dry woods and woodland clearings. The photo I loaded shows a specimen planted in a woodsy area of Longwood Gardens in se PA at the end of its bloom with a few flowers left and some dry fruit structures in early October of 2014. Sources say that it is easy to grow; can grow also in full sun; for dry or moist soils that should be acid at least a little bit; it attracts bumblebees and hummingbirds; and it blooms in August and September; blends well with Cardinal-flower and Blue Lobelia; but it is not deer resistant.
