At first I thought this was an Echeveria while visiting Heronswood Nursery in Washington a few years ago. This sedum offers evergreen rosettes of broad, rounded blue-green foliage and very pretty clusters of yellow flowers in mid- to late summer. Great for tumbling over a wall. Quite hardy over the last four winters in Vancouver in average garden soil, though sharp drainage is preferred. A collection of Dan Hinkley's from the mountains of Mexico.
Pine/agave association, growing in partial shade, in very dry soils at moderate elevations.
