Primula suffrutescens is a Sierra Nevada endemic found at high elevations on damp granitic screes and talus slopes. These seeps are kept moist by melting snow.
The plants form large mats, (I have seen several up to six foot across) with stems rooting as they run. When not in flower it is easy to mistake the plant (at first glance) for a sedum. The leaves are a yellow/ green color, thick, spoon shaped and succulent looking with a few rounded teeth along the end. When in flower there is no mistaking it's identity. There is some variance in color intensity from plant to plant.

Has anyone grown this species? When would be the best time to take cuttings?
