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.
