This is growing in a garden in Northern Virginia (Zone 7a).
I suspect it might be the dreaded Japanese Honeysuckle, but its leaves don't look exactly like the same to me. It is a young plant, just several feet high, and it hasn't bloomed yet.
Can anyone confirm its ID?
Thanks!

Compare to our native coral honeysuckle. (don't remove)
I wish we had pictures of Lonicera sempervirens at that stage (in the database).
you might even have the yellow variety.

Stone, I have Lonicera sempervirens growing in my backyard, and the NOID plant definitely isn't that (and now that I know there aren't enough photos of Lonicera sempervirens in the plant database, I'll add some!).

It's probably an Asian Lonicera species even if it's not Lonicera japonica, so I'll probably end up pulling it up. I'll leave this thread open a while longer in case others have ideas, though.

There is a lot of difference between the mature flowering size plant and the small plant that hasn't reached maturity.

The pics needed are of the small plants... before maturity... like the original picture on this thread... your pics of mature plants wouldn't help.

I would direct your attention to the blush of the stem between the leaves... I'm gonna insist that it's a native.

Strongly encourage you to wait... Or at least pot it up... When I pot the ones that accidentally get pulled, they generally are able to reach flowering size in the pots, and because I'm a lazy type of gardener... the plant doesn't get watered, or ever set out... unless, someone shows up needing one...

Oops! I was pulling up the plants at about the same time you were writing your post, Stone.
The good news is that some of the roots broke off, so I didn't kill it off in case it's a U.S. native.

Someone suggested that this is Rhus typhina, but the leaves do not look like that to me because they're entire vs. slightly toothed.

Here are a few more photos.

Not sure why people get in such a hurry...
They lose really neat stuff by pulling before getting a fer sure positive id.

Stone, I respect your advocacy for native plants.
Sometimes we make decisions based on best guesses and how much time and resource we can spend on any given aspect of (gardening) (life). I'd go nuts trying to save and rehome every redbud seedling I have no matter how much I like them.

I pulled it because I was pulling undesirable plants from semi-formal native perennial beds at a local park where I volunteer, and the head gardener came along and told me it was Rhus typhina. It would have been pulled up anyway.

After I pulled it from perennial beds at that park, I saw a lot more of it growing in another park near me, possibly deliberately planted on the edge of the path. Some kind of caterpillars had made relatively large tents on those plants. The caterpillars made me think of Dogbane or Milkweed species, but the plants don't have any milky sap so I've ruled them out.

The plants are about 2 feet tall and do not appear to have bloomed yet, so perhaps I'll get another clue soon.

I figured it out! It's Hypericum calycinum, a shrubby St. John's Wort native to Southern Europe and Southwestern Asia. I realized it when I saw more mature shrubs at the park today.

I did check out St. John's Wort photos, because I thought it looked similar to plants I had in my own garden until several years ago, but the variable leaf shape and petiole length threw me off.

Hmmm... might be...
you had up close experience with it... and there is a similarity...

took a pic at my house of the coral honeysuckle...

This is a photo of a mature Hypericum calycinum growing about 20 yards away from one of the younger ones shown in my other photos. Although not shown in this pic, the remains of its flower heads positively ID'ed it (at least for me!). The very tiny spiny points at the end of the leaves are very distinctive, too.

I will be on the lookout for flowers on the other juvenile plants identical to the one in my original post, though.

Hypericum known as St. John's wort.
Oh yes I looks very close. Wait for the flower . Soon the mystery will unravel...
