Good morning! I threw on my robe and Crocs this morning and dug it out (I thought) carefully. I took the whole thing including the surrounding soil and put it in a garbage bag and shoveled out a few leaves and flower petals in the area just to be safe. I was knotting the bag and it got me! You all were NOT kidding- I only barely got stung and it's a lingering stinging like a hornet. I'm sorry this is a repeat post, Granite. I wouldn't have known what to search for to even find the other thread but I am SO glad I posted. It sounds like you saved me and my small kids a TON of grief! The only thing I can figure is that it must have hitched a ride in the soil of my basil plant or strawberry plant I got from Lowe's. Thank you all so much for your help!

Wow, sounds like a real bad character! Thought it was unusual but guess I need to get rid of it quick, thanks!

Maybe Senecio vulgaris, common groundsel??? If so, pretty early for bloom although it is a spring bloomer. Can be tough to control as it has developed resistance to many products. Contact your local extension service for the right treatment. hortster Here is a link that might be useful: common groundsel
