MOSSES AND LICHENS 



Mosses and lichens, using these terms with their 

 popular significance, are humble specimens of the 

 vegetable kingdom not usually considered as material 

 for planting. Mosses have, however, been trans- 

 planted successfully to many gardens. They are 

 beautiful and serve a useful purpose as a carpet or 

 as a setting for small flowering plants. A professor 

 from a New England university said a moss garden 

 in Scotland was the most charming thing he saw 

 during his trip to Europe. Lichens may sometimes 

 be transplanted successfully with the bowlders on 

 which they grow. Since mosses and lichens are 

 sometimes the most attractive plants seen in woods, 

 it ought to be possible to utilize them to advantage 

 in parks and home grounds.
