Hello, I am totally new to gardening and can use all the help I can get. I have a 15x15 garden which my husband's buddy put all the seeds and starter plants in for me. I have greens growing which I am not sure what kind they are and wondering if someone could help. They resemble turnip greens with the exception that the leaves are quite smooth. I know turnip leaves to have embedded "bumps" on them. Can anyone guess what this green might be?
