I found these mystery seedlings in my garden next to the watermelon I planted. It looks nothing like the watermelon seedlings or any other seedling I planted in my garden. I am wondering if the previous owners of this house had a garden last year and this is something they had growing last year? Does this look familiar to anyone?
