I was in the finger lakes region of New York in June and came across a wildflower that blooms with a yellow trumpet shaped flower. If I remember correctly the trumpet is between 1"-2" long and the flower about 1/2" to 1" wide. I seems to be a perennial because there were dried stems and seeds from the prior season coming off the same plants. It is low and herbacious with woody stems, and about 2 1/2 to 3 feet tall. The leaves are paired on opposite sides of the branch, and each pair is 90 degrees from the next. Pairs are about 4-6 inches apart along the stem. The seed pods have two halfs (some have three), and open at the top when dried. The opening puckers open with a hole at the top but it does split down the sides a bit. Looks like the seeds are shaked out by the wind and blow away. I have attached a picture of a leaf, some seeds, and half a seed pod.
This is NOT a vine. It was almost bush like. I think it might be Smooth Yellow False Foxglove.
It was an impressive plant in flower. Purplish dark stems and naïf JFK ant yellow flowers with a neat habit. It was growing under oak tress so I think it has been identified. It is a parasite of Oaks. I've got plenty of those and plenty of seed to plant.
