 C pulchetla is one of the most showy border 



annuals ever introduced to the gardens, and is on that account 

 to be seen in every flower-garden and nursery, although but a 

 few years since its first introduction. Both species will grow in 

 any common garden soil, in which the seeds may be sown.
