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 lightest 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 potato, - 
and can be taken up in the fall, and planted in boxes or pots 
until spring, when they can either be retained in the pots, or 
replanted along the borders of the garden ; ; the latter situa- 
‘tion is however preierable, as their growth is there so much 
more vigorous, and the flowers consequently more abundant. 
The end of April, or beginning of May, isthe proper season 
for planting them out, when they will soon shoot up to the 
height of from five to eight feet, producing a great abune 
dance of flowers, of which from thirty to forty are frequently 
in bloom ona single plant at the same time. The single 
‘flowering enes possess very vivid colours; but the double 
ones, from being the most rare and splendid, are the most 
_ esteemed—twenty-eight varieties of the latter are now in the 
Lae 7 
possession of the proprietor,.as will be seen by referring to
