OK, I think I'm officially crazy! I forgot to check last night so I'm outside at 2:30 this morning with a flashlight checking them out! I hope no neighbors saw me....
The first picture is Nouveau Pastel, the second one is Lilac Queen. But I also have a few others in that bed that did the same thing: Jubilee, Glaucum Minor and Leocadia. These were not all purchased from the same source and they were all fine when I planted them last year. This is a new development this Spring.
Haven't heard back from Squaw Mountain yet. I'm sure they're really busy right now and it might be a while.
