Thanks, Janice!
Those Tulips look like a group known as the "Temple sports", various sports of "Temple of Beauty". I believe 'Perestroyka', 'Hocus Pocus', 'Temple's Favorite', 'Blushing Beauty', and 'Blushing Lady' are all sports of 'Temple of Beauty'. They're classified as late singles, but bloom earlier than other late singles for me, and occasionally show some mottling in the foliage, which makes me wonder if there is Gregii parentage. I've seen mixtures of them offered from Colorblends and VanEngelen (John Scheepers) catalogs.
