A single Tiarella by itself is an exceedingly beauti- 

 ful plant but it also grows in mass stifficiently to make 

 an impression by niunbers. The many long-petioled, 

 heart-shaped leaves spring from the horizontal root- 

 stock or from the runners that the plant sends out. 

 Any plant that develops runners forms beds. By
