Campanula waldsteiniana xera A sea holly that transformsA low, evergreen mat with textured leaves and wide blue purple flowers in summer, ideal for sunny rockeries or alpine crevices. Dalmatia, Croatia: limestone rock crevices. Interesting foliage and blue purple, wide open flower, this is a special plant in the alpine garden and rockery. Violet flowers in summer. Stoloniferous so it forms an evergreen carpet. Likes a bit of lime, but neutral is fine too. Sun. 12cm Wikimedia Dario Taraborelli, CC0, via
