The Kabschias are extremely

enhances the beauty of the rosettes of foliage even during 
winter. The mossy kinds will thrive quite well in ordinary 
soil, but it is advisable from time to time to mulch with 
gritty sandy compost, working it well down among the 
stems beneath the cushions of foliage.
