Shade is necessary for all plants in their infancy, or when the} 

 are diseased, or when they have suffered violence by removal. 



. Seeds germinate best in obscurity, and are best when shaded for a 

 few days after. The clouds furnish shade often, but art uses means 

 to give shade to them. Seeds that must be sown on the surface or 

 with little earth over them, grow best if shaded for a time. 



Shade is necessary for such flowering plants as are desired to pro- 

 long their flowering and freshness. Shade is important to all plants 

 in slips, it is almost indispensable in order that they may root well; 

 plants in light, purify the air by absorbing carbonic acid and disen- 

 gaging the oxygen, and they corrupt the air at night by suffering 

 carbonic acid to escape without being decomposed. 



ROSE GARDEN. 



From Annales De La Societe Rot/ale D^ Horticulture Be Paris. 



It is now nearly three thousand years since the rose was first call- 

 ed the Queen of Flower^ s. I fear not to say that, none of the ancients, 

 not even the Greeks or the Romans, knew truly the merits of this 

 delicious production of nature. Even w-e, until within the last fifty 

 years, were very far from knowing the value of Roses. At a late 

 date we had but quite a small number of Roses, of little variety in 

 form and color, in our gardens. There was not among them any to 

 be seen of those varied shapes and splendid colors which have re- 

 cently been produced by an intelligent and careful culture. And 

 those beautiful flowers were transient — the bloom of only a single 

 season, so that we were entirely deprived of them for the greatest 

 part of the year. There was but one rose, which was vulgarly called 

 the Rose of Four Seasons, which occasionally gave its flowers in the 

 Autumn, but that was very precarious. Now, however, the whole 

 face of things is changed. Roses have been multiplied in kinds and 

 colors by planting their seeds repeatedly, and by a more knowing 

 cultivation; exhibiting now more perfect and diversified varieties of 

 an infinite variety of shades of color, of perfume, and blooming at 

 all seasons of the year. The ancients called their Rose Gardens, 

 Rosaria. 



Monsieur Loiseleur Deslongchamps, who visited the Rosaria of Paris 

 and its environs, says, that he had examined that of M. Victor Ver-
