I'm not positive, but I think this is a succulent known as a flowering Echevaria plant. This photograph has been featured a couple times on Instagram and entered in a "Pastel Challenge" internet contest. The winners are to be announced today!
It's one of my better ideas. It doesn't cost me anything. I takes only a few minutes. My wife doesn't have to tend to the flowers. She appreciates them as she would appreciate real flowers. Finally, not only does it remind her every day that I love her, it reminds me every day that I love her!
