Try posting again when the first true leaves are open. And since it volunteered, I would leave it outside since it likely is hardy. You also might want to add a tag for the Name that Plant forum if you still can since that is specifically do plant ID and there are some real experts there. go to edit the post, and then find the place where you can check your desired forums to add it. You have a relatively short window of time before they close down the edit open,just a few hours.

Will do. I did a name that plant in the search box but nothing came up. Where does one find that?
