green_go - if a plant isn't native, you always run the risk of introducing something which may become invasive in your garden conditions. Once you factor in moisture, soil components and natural predators, it's always wisest to think twice before planting something unless experience has shown that it behaves in your garden. Certain native species can also run rampant when planted in areas where they aren't traditionally native. Have I erred when planting certain perennials after hints on this forum suggested they were invasive? Let me count the number of self-sown seedlings I've regretted. I've no experience with Filipendula since I've never been tempted to plant it. I just make certain I've done my homework before digging a planting hole or setting something in it. Not planting something has been my guide and = less regrets.

oh man, that's definitely jewelweed. you DON'T want to introduce that to your area :P it spreads like crazy cause the seeds shoot everywhere like Linda said. we cannot get rid of the stuff around here - I live in a freaking swamp, so it's to be expected :P but in all fairness I'm part of the problem cause I always have to play with the seed pods, LOL. my grandmother taught me the name "touch-me-not" too :D I learned years later that the plant was actually called jewelweed. it's seriously the juiciest plant I've ever seen, lol.

Thanks ginibee but after looking up borage it doesn't quite fit the bill. It could be a wild origin plant, not a cultivar so perhaps it is in that family. It has come back two years in a row now and the bees and butterflies love it, doesn't last all summer but drops seeds that come back in spring. I will keep trying, perhaps someone will recognize it.

I believe that's Symphoricarpos orbiculatus, usually called Buckbrush here in TN. Another common name is Coral Berry. It's actually quite a pretty plant when well grown.
