Cult. Fagonia is a genus of pretty little shrubby looking 

 plants. They are only to be increased by seeds, which should 

 be sown in pots in autumn, in a light rich soil ; these should 

 be placed under a frame in winter ; in spring several of the plants 

 may be potted off" in separate pots and placed among the green- 

 house plants, others may be planted out in the open border, in 

 a warm sheltered situation, 10 inches apart; thus they will 

 flower early and ripe seeds may be obtained. The shrubby 

 species hardly last more than three years, therefore care should 

 be taken to preserve their seeds.
