Cult. These beautiful plants deserve to be cultivated in every 
collection ; the seeds only require to be sown in the open ground 
early in the spring in a warm dry situation, in light soil. If 
kept in pots, as greenhouse plants they will endure several years, 
although said to be annuals ; in this state they will flower very 
early in the spring. They are all propagated by seeds or cuttings.
