useful on rockeries and rough banks, where, having been 

 sown once, they will in many instances obtain a per- 

 manent position by means of self-sown seed, which are 

 freely scattered if the plants are left alone. Corydalis 

 glanca and Fnmaria capreoluta lutea may be mentioned as 

 good examples of this class of flowers. There are many 

 first-class annuals that maintain themselves by self-sown 

 seeds — as the mignonette, nemophila, eschseholtzia, and 

 others.
