This plant is open during the day and closes at night. Sorry if the pictures don't come through. This is my first post. Thanks for the help.
Albizia julibrissin Common names Silk Tree, Mimosa Tree [not to be confused with the Mimosa genus (monkey flower) which are herbs (stems not wooody)] Harry
Leaf shape seems a little different from that one, nor have I seen it with such bloomy-looking leaves and stems before. http://images.google.com/images?q=j...a&rls=org.mozilla:en-US:official&start=0&sa=N Did the seeds originate from local trees or was it something acquired elsewhere, that might not even be cold climate adapted? If gathered from trees overwintering for many years outdoors near there silk tree is pretty much the only candidate.
Thank you both for your help. This plant was found in my mother's flower bed in northern Illinois. She thought it was a weed, but dug it up and replanted it out of curiosity. Upon further investigation, she found out the bedding plants she planted were from Alabama. So we are guessing this plant hitched a ride up north in the bedding soil. She said it is aggressively growing and is anxious to see what it will do. Thanks again.
