Cult. These pretty little plants will answer well for orna- 

 menting rock-work, or to be kept in small pots and placed among 

 other alpine plants. Those cultivated in the latter way should be 

 grown in a mixture of sand, loam and peat, and the pots should 

 be well drained with potsherds. They may either be increased 

 by cuttings planted under a hand-glass in the same kind of soil, 

 or by seeds.
