CULTURE OF A FEW ORNAMENTAL PLANTS. 
ever, that so many of them appear to require a high temperature, while only a yery 
limited proportion will flourish in the cooler houses, with which alone many small 
places are furnished. Hence the lesser cultivators, who would gladly comprise 
such beautiful things in their collection if they could be induced to thrive in the 
sole receptacle they possess, — a common greenhouse, — have to forego that pleasure 
on account of their tender nature. 
If the fact we are about to submit should have any tendency to alter the 
general impression regarding the tenderness of Passion-flowers, and so facilitate 
their admission to greenhouses more universally, or prompt individuals who have 
no stove to experimentalize on their capacity of enduring cold, we shall be exceed- 
ingly gratified ; because we consider that, by demonstrating that a handsome plant 
or tribe of plants may be grown with less heat than is usually given, a grand point 
in its culture is gained. 
The species concerning which we now have direct evidence to offer is P. qua- 
drangularis^ (or Buonapartea^) a plant which, from the freeness and richness of its 
growth, and its palpably tropical character, may be reckoned one of the species 
which would seem to demand the highest temperature ; and which, from the same 
considerations, would be thought least likely to submit to greenhouse treatment. 
A plant, however, in the conservatory of Colonel Long, Bromley Hill, Kent, has, 
this summer, bloomed in the usual prolific manner, and the flowers were even 
somewhat larger than they commonly are in a stove, and very much richer in 
colour. The specimen, from its size, has no doubt stood there several years, and is 
planted in one of the borders of the interior. At another place in Kent, we noticed 
a specimen of the same species in a greenhouse, and the foliage and flowers were 
fully twice the ordinary dimensions, the latter being of a most superb colour ; but 
the blooms were scanty, and late in making their appearance. 
On comparing the conditions in which the plant was kept at both these seats, 
we perceived clearly that the liberality with which the first bloomed, and its 
similarity in beauty to the stove state of the species, were attributable to its being 
grown in a conservatory, attached to the residence, higher and darker than the 
structures distinguished as greenhouses, and, not being so freely ventilated, having 
a somewhat moister atmosphere. Wherever, therefore, the same conditions can be 
realized, we may venture to assure the reader that there can be no risk in cultivating 
this superb plant ; and would further suggest that, as others of the genus come, for 
the most part, from similar latitudes, they may most likely be subjected to an 
equally diminished temperature with the like satisfactory results.
