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,
