What plant is this
I found this plant or weed in my yard, and suspect it's an off shoot of some hybrid poplars I planted and cut down. But I am looking for identification on the plant because it's quickly spreading in my yard
I suspect that these are poplar suckers coming up from the roots of the tree you cut down. You may want to bring a sample to the Master Gardeners at the UConn Extension Center in North Haven for a positive ID. Their number is (203) 407-3161.
