what is a good variety of hearts or plums (or Romas) for someone that likes a variety of colors and tastes? I haven't grown more than some Burpee Romas which were okay, and some random mystery oxhearts of various colors, which were better. I also had some San Marzano this year (I got in a trade with another local gardener). But I really am getting into various color's and shapes tastes, so would appreciate a smallish list with a good variety of tastes, but still good for cooking. I would like to hear about good dark ones and also good yellows, pinks and reds.
