Ever since we bought plants from the late Helen Payne of Oak Hill Gardens near Dallas, Oregon (and author of Plant Jewels of the High Country), we've grown and enjoyed a wide variety of Semps. They're great plants with much more to offer than one would guess from their common name "Hens and Chicks". Some of the cultivars are really quite outstanding. This example is called 'Saturn'. In our area they're really quite easy to grow, though I understand that in some of the drier and hotter areas they can present a bit of a challenge.
