I hear ya, Susan. At least a few of my semi's and one evergreen went dormant, and they were all normal semi/ever's before. In my case, each of them had bloomed valiantly through last year's scorching summer, were moved to a new garden spot in late fall, and had gone at least one year without fertilizing, so I think mine did indeed get stressed and that resulted in their defensive action of going dormant.
It was alarming enough that I made notes in my records that "they might be dormants in my climate!" ... well, they might be ... but, now that the weather is warming up they are all coming back well. It was a bit alarming, though, for the months that their garden spots were bare!
