changing from white to blush colour and then to purple, thereby ~

Mibiseus rosa sinensis, the different double varieties of this shrub 
are extremely beautiful, perhaps none more so than the double 
crimson, which has a richness rarely excelled; the different varie- 
ties of this plant are among the most desirable appendages of the 
Green-house. | 
DATURA ARBOREA, er 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 a 
agreeable fragrance, and are generaliy near a foot in length. 
DAHLIA, 
- Of this beautiful plant, more than 150 varieties are now cultivated 
in Europe, many 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 situation is however preferable, 
as their growth is there so much more vigorous, and the flowers 
consequently more abundant. The middle or end of April, 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 abun- 
dance of flowers, of which from thirty to forty are frequently in 
bloom ona single plant at the same time. The single flowering 
ones possess very vivid colours; but the double ones, from being 
the most rare and splendid, are the most esteemed. The collection 
now in the possession of the proprietor, is not surpassed by any in 
the world, and consists of 73 double varieties. See page 102. 
“CONCLUSIVE REMARKS. 
It will be perceived by persons who are connoisseurs of flowers, 
that very extensive acquisitions have been made to the Green-house 
collection of the most rare, beautiful, and valuable species, and in 
doing this, the proprietor has rather consulted the aggrandisement 
and extension of the establishment, than a particular regard to 
pecuniary benefit to himself; and very many of the plants have been 
purchased at an expense of from one to fiye guineas each,
