eral species, all good and showy i)laiits, having large umbels of 

 ample, pure wiiite, very fragrant flowers. P. maritiviuin, corona- 

 rium, rotatum, occidenlale, and nutans all require greenhouse 

 culture. 



Leaving this class, we come to the 



Annuals, or such plants as spring up, flower, perfect their 

 fruit, and perish within a year ; ])ut as in every rule so here we 

 find exceptions. Some plants present in cultivation the same 

 characteristics as annuals proper, but in their native places and 

 conditions they are either biennials or even true perennials. 



Many very ornamental and showy plants belong to this class, 

 and being mostly' of easy culture they are oftener seen in our 

 gardens than other plants ; yet there are many valuable kinds 

 that would be desirable additions to the list of those already cul- 

 tivated. 



The}' are propagated mostly from seeds, although some may be 

 propagated by cuttings ; the former method is the best and the 

 one generally practised. The seeds should be sown in March, 

 either in the greenhouse or hot-bed frame, and the young plants, 

 when large enough, should be potted in small pots, and at the end 

 of May planted out. Where there is no such accommodation, 

 the seed could be sown out of doors in the latter part of April or 

 the beginning of May ; but in this wa}' the majority of plants 

 would flower rather late. 



A very good way is to sow the seeds of such plants as Phlox 

 Drummoudi, and several others, in July or August, and keep the 

 plants over winter in a cool frame, such as is ordinarily used to 

 winter the Pansy. If treated in this way they could be planted 

 out in April at the time they begin to flower, and would cjntinue 

 in bloom the whole summer. All plants of tiiis class require 

 good, rich, well-drained soil, and the full benefit of light, air, and 

 sun. 



Among tlie cream of Annual Plants we have Phlox Driim- 

 mondi^ with its numerous varieties of almost every color. 



We next mention Gaillardia 2Ji'Cta and O. amblycodon, witli 

 tiieir large reddish flowers. 



All the species of Coreopsis are ver}" showy, such as C Drum- 

 mondi, C. (•ardaminifulia^ and C. tinctoria, and all have yellow or 

 jellow and rod flowers. 



The genus Nemophila includes many beautiful and delicate ver-
