I think Ridge nailed it. Rhexia virginica
aka "Handsome harry" (I don't know why they don't capitalize "harry", it's a proper noun). You need to show us a picture of it when it's in bloom Cane. It's flower reminds me of a clematis bloom. Interesting plant!
LOL Ridge, Google is not my friend. I go looking for 'vase plant pods' and end up 2 hrs later learning how to turn a tire into a planter... and never find the plant pods....
