Polly I have not read any books on them , mostly internet research and talking to people at garden centers.
Anna for pink I would go with Cotton Candy or Peppermint Ice.
Evan I know that they are sold as shade plants , but that is because they do well in shade and in the south they need shade . But in the northern states they can take plenty of sun. I have some in my sun garden that get full sun most of the day and they are almost 3ft wide now. I find they do better with sun. They do not like to be crowded or to be kept wet this can lead to fungus problems.
