Nursery contributed plant descriptions

A Cistus introduction. A common native of western dry lands, this clone, from northeastern Oregon's Imnaha Canyon, was found weeping several feet off a cliff of red ryolite, the nearly spineless, gray-blue pads appearing almost as if hanging in chains. Assuming not everyone has a cliff, these will form spreading mats to 4-12" tall and up to several feet wide. Early summer flowers are a warm, soft yellow. Ordinary cactus requirements -- sun, lean and well-drained soil, and little or no summer water. Undoubtedly frost hardy into USDA zone 4.
