All the wildflowers have gone to fruit and seeds. This shot is from November 19. Wahoo is a Dakota term for this plant, which means “arrow wood.” Native to North America, related to bittersweet and also to the non-native invasive kind of euonymous.
Eastern Wahoo (Euonymous atropurpureus)
I would probably think I’d found bittersweet if I saw it!
No you wouldn’t, because Eastern Wahoo is a small tree and bittersweet is a vine. The wahoo looks more like a little fruit tree.
