Cult. All the species of the Willow-herb are of the easiest 

 culture and propagation ; they will grow in any common gar- 

 den soil, and are easily increased by dividing at the roots or 

 by seeds. Those species belonging to the first section of the 

 genus being the most shewy, are the most worthy of cultivation, 

 as border flowers.
