Some choices are to use pre-emergents chemical herbicide products like Preen, plant a non-seeding variety (to avoid this problem completely in the future), deadhead the spent flowers (now and every year), pull them by hand (sometimes I prune the bulk of the small plants and they do not return), cover them with cardboard for a few months or very carefully paint them with a regular herbicide for woody plants like Bioadvance's Brush Killer or Ortho's Ground Clear.
