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.
