Cult. Arenaria is a genus of dwarf herbaceous plants, for 

 the most part perennial, the most of which are well adapted for 

 ornamenting rock-work, but some of the rarer species should be 

 grown in small pots well drained with potsherds, in a mixture of 

 sand, loam, and peat, and placed among other alpine plants. 

 Those species marked frame only require to be sheltered during 

 frost. The perennial species may be either increased by divid- 

 ing the plants at the root, by seeds, or cuttings planted under a 

 hand-glass will root freely. The annual kinds are not so shewy 

 as the perennials, therefore they are not worth cultivating, except 

 in botanical gardens ; they may be either sown on the rock-work 

 or in the annual arrangement.
