This has started growing in a couple of my beds and planters. I have not seen it before in my yard and am wondering if it is a weed, or escaped seed that I've forgotten about. Thanks in advance for any help.
A "weed" is a plant you do not want growing where yo udo not want that plant to grow. If this is a "weed" or not depends on whether you deterine it is or not.
Thank you for your helpful response.
