Petrophytum Caespitosa

This delightful, bone hardy, extremely dwarf shrub is native mainly to California and is confined to rocks and crevices in the mountains of the interior of western North America. It displays its evergreen blue-green tufts, and attractive, small bottle brush-like white flowers in summer and does well in sun or part shade in very sharply drained soil. In cultivation it will do well in trough, crevice garden or scree bed and will make a good pan for an alpine show.
