DATURA ARBOREA, or Great Peruvian Datura, 



This plant, which is of vigorous growth, produces 

 very splendid flowers during the months of October and 

 November; they are pure white, of a pentangular 

 form, with angular extensions, possess an agreeable fra^ 

 grance, and are generally near a foot in length. 



DAHLIA. 



Of this beautiful plant more than 150 varieties are 

 now cultivated in Europe, 34 of which have double 

 flowers. It is a native of Mexico, and the flowers are 

 of every gradation, from the darkest lake colour to the 

 lighest shades, and of every hue but green, and, in 

 splendour, they are surpassed by those of no other plant. 



The roots, which are tuberous, resemble a sweet po- 

 tato, and can be taken up in the fall, and planted in 

 boxes or pots until spring, when they can either be re- 

 tained in the pots, or replanted along the borders of the 

 garden ; the latter situation is preferable, however, as 

 their growth is there so much more vigorous, and the 

 flowers consequently more abundant. The end of April, 

 or beginning of May, is the proper season for planting 

 them out, when they will soon shoot up to the height of 

 from five to eight feet, producing a great abundance of 

 flowers, of which from 30 to 40 are frequently in bloom 

 on a single plant at the same time. The single flowering 

 ones possess very vivid colours; but the double ones, 

 from being the most rare, are the most esteemed — 23 

 varieties of the latter are now in possession of the pro- 

 prietor, and will soon be sufficiently increased for dis- 

 tribution*
