Perennial from the Saxifragaceae family, this cultivar comes from a collection made on Mount Maglić, the highest point of Bosnia and Herzegovina at 2,386 meters, a limestone massif of the Dinaric Alps at the borders of Bosnia and Montenegro. S. paniculata colonizes the rocks, ledges, and exposed limestone cliffs there.
What immediately strikes in this form is the size of the rosettes, significantly larger than the average of the species, and the particular morphology of the leaves. These are elongated, narrowly spatulate to almost tongue-shaped, a dark green to dense gray-green, with a discreet but regular white limestone border on their edges. The longest leaves of the adult rosettes give them a spreading and vigorous appearance, very different from the compact and tight forms frequently encountered in this group.
The plant forms dense and vigorous mats, with the rosettes actively multiplying to gradually cover a notable surface. The whole gives an impression of robustness and unusual vigor for a saxifrage of this group.
In its natural habitat, its flowering extends from June to August. In cultivation, it generally occurs in May-June, with panicles of white flowers on rather slender stems.
It requires a well-drained substrate, preferably limestone, in full light, without stagnant winter moisture. Its vigor makes it more accessible than some delicate forms of the group, while retaining the pronounced mountainous character of the species.
