There is no way I could just pick 5 or even 10 as my favorites. I love them all that will grow for me. I tried Foxglove and Shasta Daisy but did not have them come back. I have also tried Daffodils but they did not come back either. I still have a lot of space to put flowers so I will be adding many that I don't have yet. Visit my blog and you will see some of my flowers and flower beds. Happy Gardening!
