This is only a guess with some 80,000 registered cultivars, but the first image shown might possibly be Ned Robert's PURPLE MANY FACES. It is definitely not Purple Pinwheel! Here are a couple of images as PMF grows here for comparison to the first picture. The distinct white midrib shown in the other DB images would show even at the end of the day, ( it isn't apparent in the first picture) and the form of the two flowers is not the same!
