    Campanula shetleri is native to California in the Mount Shasta and Trinity Mountains areas, where it is usually found in shaded crevices in north-facing granite cliffs. Leaves are spatulate and serrated and form dense, low rosettes. The woody rhizomes prefer a cool root run. Flowering stems are 5 - 7 cm tall; flowers are small, bowl-shaped and range from white to gray blue to deep blue. It is small enough to be ideally suited to a trough.

    Ref.: Dwarf Campanulas and Associated Genera, Graham Nicholls, 2006.

    Can be challenging to grow, particularly in areas of winter wet.
