Perennial of the Saxifragaceae family, this selection or form collected in Austria is distinguished by the remarkable compactness of its habit. It forms a very dense and regular cushion, composed of numerous small rosettes tightly packed against each other, forming a firm and homogeneous dome that can extend laterally over several tens of centimeters while remaining low in height.
The leaves are short, spatulate, of a strong medium green, and bear the characteristic white edging of the species, here particularly clear and regular, which outlines the contour of each rosette and gives the whole a texture almost geometric, akin to the work of plant goldsmithing.
The designation 'ex Austria' likely indicates an Austrian collection origin rather than a cultivar named in the strict horticultural sense; the available information on this form remains limited and it is worth noting.
In cultivation, as with the type species, it requires a well-drained substrate, preferably calcareous, in full light. Its exceptional compactness makes it a choice subject for troughs and well-tended rock gardens where precision of habit is sought.
