water, they will soon show flower at the end of every shoot, and 
if removed to a close part of the conservatory just as the buds 
begin to assume their blue colour, and protected from damp, they 
will remain in this state for some three or four months, for they wilL 
hardly open in the temperature of the conservatory, and in this 
state they will have a very pleasing appearance. 
The flowers will, however, open freely in the temperature of an 
intermediate house, where, if the roots are well supplied with weak 
manure water, and a moderately dry atmosphere maintained, they 
last long, and, on plants that have been properly ripened, will be 
produced in succession from the side shoots for months. 
Specimens intended to be grown on for further use, must be cut 
back in time to allow of their making a short growth before winter, 
and should be repotted every other year ; but by supplying them 
liberally with manure water, they must be kept in health in good- 
sized pots for several seasons without repotting. The best soil for 
this plant is three parts good strong fibry loam, and one part peat, 
or leaf-soil, mixed with a proper quantity of sand and lumpy bits of 
charcoal, to keep it open and porous ; for if grown in light, rich soil, 
the wood is apt to be long-jointed, and the specimens rather inclined 
to straggle. 
GARDENIA. 
HIS is a lovely and well-known genus of plants, which are 
extensively cultivated for their odoriferous properties, 
as well as for their beauty. It is scarcely possible to 
single out a more attractive tribe than this, or one that 
is a greater favourite with the public. Gardenia radi- 
cans, G. Elorida, and F. plena (the well-known Cape Jasmine), are 
inhabitants of every hot-house, and, during summer, we may add, 
of almost every drawing-room. 
In the bouquet, also, the addition of a flower of this plant dif- 
fuses a most delicious fragrance. 
According to Thomberg, the notable Cape Jasmine is highly 
esteemed with the Japanese ; they form hedges round their dwellings, 
and introduce it with great profusion in their gardens. Gardenia 
Rothmannia is a spotted species of considerable beauty ; its fra- 
grance is most sensibly diffused during night. 
It is a plant of great excellence, and, like the following, deserves 
a place in all choice collections. G. amoena is an interesting stove 
shrub, of dwarf habits, retaining its natural spines very often under 
cultivation in this country. All the species are more or less prickly 
in their native state, but they appai’ently lose this when they are 
subjected to a higher degree of artificial cultivation. There are 
other species of Gardenias known to our gardens, although not cul- 
tivated, being either less remarkable for their beauty or their fra- 
grance. The propagation of the Gardenia is exceedingly simple ;
