Nursery contributed plant descriptions

Extremely tough and easy to grow succulent groundcover that forms a tight mat of evergreen foliage and a long-blooming display of bright yellow flowers that open in the afternoon sun. Water regularly in summer but allow to dry out between. Needs little to no winter irrigation, so valuable as an attractive potted specimen planted in porous soil. Part sun to full sun, if acclimated. Frost hardy to -10 degrees.
Yet another of the "Hardy" Delosperma-like mesembs (hardy in Denver's zone five has become something of a joke around here, which is why I have such disdain for zone maps). It survived the winter here but died in the spring mushy season, like most of them it needs it dry to make it, but it is easy to bring a piece inside, they root like weeds.
