Purple saxifrage (Saxifraga oppositifolia)

Another rock-breaker, as its Latin name suggests ( means rock-breaker), grows in barren, rocky landscapes in all kinds of cold temperatures.

It is an evergreen cushion-forming perennial, which forms alluring magenta to pale pink or white cup flowers.

Although the plant isn’t easily available, it can be grown in gardens if planted in very dry spots. It can also be used in rock gardens to “break up" the rocky scenery.
