Cult. All the species of this genus are elegant, and therefore 

 well fitted for decorating flower borders. They grow well in 

 common garden earth, but prefer a dry sandy soil. The seeds 

 of annual species require only to be sown in the open border, 

 where they are intended to remain. The perennial kinds are 

 readily propagated by division of the root, or by seeds. The L. 

 alpina, L. supina, L. tr'ut'u, and some others, are well fitted for 

 ornamenting rock-work, or to be grown on dry banks, or in pots, 

 and placed among other alpine plants ; these in winter require 

 to be sheltered from the frost, as well as all those marked frame 

 or greenhouse. A great part of the species are readily increased 

 by the surculi, which will strike root readily if planted in sand ; 

 and all are to be increased by seed.
