My new favorite is "Queen Lime" (pictures 3,8, 11 and 12). I took a million pictures, and kept a small bouquet next to my bed throughout the summer. I also liked the regular, cut-and-come again type. I also like the little tiny ones.
I bought my seeds from a few different places, but next year I think I'll stick with Johnny's and Burpee. I bought the Queen Lime's from Johnny's.
