Looks like a Penstemon, though a photo of the whole plant would make a positive ID more likely.

I was thinking Penstemon too.

Or maybe Angelonia.

Compare to Calico Beardtongue (Penstemon calycosus)

If you found it in the wild in VA, there are just a handful of other Penstemon species native to the eastern states.

There are also many Penstemon hybrids, but that looks like a species to me...

Looks like a Penstemon to me.

Here's a whole plant shot. It's in a cultivated garden.

Looking at the purple stems... makes me to wonder if possibly the original plant was purchased as huskers red:
Foxglove Penstemon (Penstemon digitalis 'Husker's Red')

And maybe some seedlings came up with a reversion to green foliage.

I used to have naturally occurring penstemon digitalis at my previous garden... too dry here in the sand for it to grow... miss it.

I'd be tempted to thin out some of the monarda... Give the penstemon more of a chance to show...

Due to the distinct form of the stamens inside the flower, it is a penstemon and definitely not an Angelonia.

It does look like a kind of Penstemon digitalis. Husker Red is also a type of P. digitalis.

Description

Close-up of flower blooming in Schenley Park, Pittsburgh
Penstemon digitalis is a glabrous 3 to 5 foot tall herbaceous plant with opposite, shiny green, simple leaves, on slender, purple stems. The leaves are up to 5 inches long. While upright, the stems average anywhere from 2 to 3 feet tall. The flowering panicle extends to almost one third of the plant's height and has pairs of branches which repeat with two flowers multiple times. The pedicels are almost one fourth of an inch long and produce 1.25 inch long two-lipped tubular flowers over dark green foliage. The flowers have tiny white hairs on the outside of the tube. The plant has elliptic basal leaves and lance-shaped to oblong stem leaves.[5][6]

The species was originally described as "Fox-Glove-Like Pentstemon" (sic) and the specific epithet digitalis is a direct reference to the foxglove genus Digitalis. The plant grows in moist, sandy soil in full sun in meadows, prairies, fields, wood margins, open woods and along railroad tracks.[5][7] Its bloom period is from late spring to early summer. The plant is known to attract butterflies, bees, and birds such as hummingbirds. It tolerates deer browsing.[5][7]
