Haven't We Met Before?

 While I was waiting for Rachel to pick me up after today's immunotherapy infusion, I saw these beautiful flowers in front of St. David's. I feel that I should know what they are, but I don't. If you do, let me know.....Update:  just had a friend tell me that the flower is a dianthus.  I looked it up and I do believe that she is right---thanks to my friend, Linda, for the info!
