Cult. Many of the species of Trefoil are very shewy, and 

 very fit for ornamenting flower borders. All the species will 

 grow in any common garden soil. The perennial kinds are easily 

 increased by dividing the plants at the root in spring, or by seeds, 

 which always ripen in abundance. The seeds of the annual kinds 

 only require to be sown in the open border. Those species 

 marked frame and greenhouse only require to be protected in 

 winter.
