inferior. There appears to be no limit to the varieties 

 which may be obtained from seed, consequently we advise 

 every one, who has time to spare and land in which to 

 plant them, to try and make improvements npon those we 

 now possess. 



It is not every plant that bears seeds, for our florists 

 have reached the adfinem with some kinds, and produced 

 flowers so double that the organs which are necessary for 

 producing seeds are entirely wanting. But such plants 

 are comparatively few, and there is still abundant room 

 for progress with other equally beautiful kinds. 



We meet the same difliculty when we endeavor to make 

 a select catalogue of choice kinds from this c-lass, as we 

 have in the others. The varieties are so numerous that it 

 is scarcely possible to say which are the best. The follow- 

 ing are all good and hardy in most of the Northern States. 

 The i^rincipal color, height of plant, and time of flowering 

 are given. The time is for the latitude of New York city, 

 which will vary in proportion as they are grown north or 

 south of this latitude.
