Looks like you have Burning Bush, Cork Bush, Winged Euonymus - Euonymus alatus http://davesgarden.com/guides/pf/go/1705/ There is a reason it "just appeared"; it is invasive and you probably have more, or will. It gives nice color in the fall, but it will spring up throughout your property, as well as your neighbor's. Give serious consideration to keeping this out of your yard.
Its in a bed of dense pachysandra which we and neighbor share so I'd better yank at it before it recovers from the weed whackers and spreads. I read your link and negatives outweigh the potential nice red foliage in fall and we have many other berries from plants (I might ask for ID on those) growing wild in same area to feed the birds.
So thanks! Guess this solves the question! Do I mark it solved or should you do it? Or should I leave it open see if anyone else has a comment to make before I yank at it!
You're responsible for marking the thread solved once you're happy with the ID. (if you look up right above your original post, you should see a question asking you if it's solved and there's a link to click to mark it solved) People can still post on the thread once it's solved if anyone has additional comments, so as long as you're satisfied that the plant has been ID'd correctly I'd go ahead and mark it solved.
Yank it, as greenthumb recommends - and any others that you come across. Your advocacy for fruiting plants native to your area is the better approach, and among those choices you will find so many that offer other benefits to you as human and to all the fauna that wish to share in the bounty. A couple viburnums wouldn't be bad...
Yes I have huge old ancient Viburnum (Snowball variety name from its fragrant white blossoms) in front yard away from that area, so do not need any invasive plants anywhere to compete. It is SOLVED! Thanks again!
Just marked it solved and updated my info. Does anyone know the difference between a zone 7a and 7b? I see some of you have a and b too and the Agriculture map (Great map! I'm saving it!) does not mention a's or b's.
Thanks! (unless there is a spot better for this question to be asked on Forum)
I think the difference is about 5 degrees Fahrenheit...but for this purpose it isn't a difference to lose much sleep over, since it is based on relatively recent average temperatures.
Knowing a bit more about your location (state, town, soils, rainfall, etc. - as much as you are comfortable providing) makes it tremendously easier to help ID your plants, since the climatic zones range around the world. They are quite distinct even within the zone 7 range in the northeast US.
