Cult. These are pretty plants with yellow flowers. The pe- 

 rennial species are well adapted for ornamenting rock-work, or 

 the front of flower- borders ; they prefer a dry sunny situa- 

 tion. The annual kinds should be sown in the open borders, and 

 if sown at different times throughout the season a succession of 

 flowers may be kept up. A light sandy soil suits them all best, 

 and as they all produce seeds in abundance they are therefore 

 easily increased.
