Cult. The species of this genus are hardly worth cultivating 

 except in general collections, as in botanical gardens. The pe- 

 rennial species may be grown on rock-work or in borders ; they 

 are readily increased by seeds. The biennial and annual sorts 

 may be either sown on rock-work or in open borders. All the 

 species succeed best in a light sandy soil.
