it looks similar to coneflower, but i can't tell if the leaves in the picture are rounded or pointy...

I don't have poke that grows at my place but I do have lots of Bittersweet Nightshade (Solanum dulcamara). I remove it from gardens, but I didn't go nuts (as many do) when my kids were tiny trying to nuke it and "protect them" from it. It provided a good teaching tool for berries that look edible but are not. I made sure they knew exactly what it looked like - just seeing it helped reinforce plant safety lessons. Poke can also provide that same learning and teaching experience. FataMorgana

Wow, what a bunch of experts. Yes, that looks just like it. The only difference is that the ones I found were a much brighter pink. Those must be it, though. They don't seem to have any particular use other than just being interesting to look at. Perhaps I can go back and find one to put in the yard. Thanks for your help!

Probably Jasminum beesianum
