Here is the native Goldenrod that grows here. It's taller this year because of the rain measuring about 22" max. It won't get much taller and it won't bloom 'til fall. You can see that while it's a uniform and neat growing plant, it's clearly different than the one that started the thread! I can see where it might be a nuisance because it spreads underground, but it's taken a long, long time for this to spread this much around the propane tank. An advantage to having a native pasture staked off for a yard is experimenting with keeping plants that are already in place
