This excellent group of rock garden plants is known as the section Ligulatae, or more commonly as the silver or encrusted saxifrages, in recognition of the deposits of lime that line the leaves. They all have rosettes, large or small depending on the variety, and have relatively large panicles of flowers, usually white. They come from rocky places in the mountains, some on limestone and some on acid rocks.

Saxifraga 'Lantoscana' is regarded as a form of Saxifraga callose by some, and of Saxifraga lingulata by others. There is also 'Lantoscana Superba'! Whatever the name, it is a lovely, compact silver saxifrage with rosettes of slender leaves, heavily lime-encrusted, which can make a dense clump. It has long arching stems bearing pure white flowers at the tip and along much of the length.
