GREENHOUSE CLIMBING PLANTS. 
How speedily, and with what particular plants, the system thus hurriedly 
exhibited may be carried into effect, experience and the judicious institution of 
every appropriate experiment and test can alone indicate. Our present object is 
to point out a few of those more graceful greenhouse climbing species which we 
have seen employed for ornamenting the pleasure-grounds. And having previously 
(p. 159, August No.) stated the plan of training and the form of trellis we would 
wish adopted, it now devolves upon us, as then promised, to make a selection of 
the most suitable kinds, and say a few words on their individual management. 
We cannot commence better than by specifying the genus Tropjeolum, in 
which will be found several elegant species, particularly adapted for flower-garden 
display, or for distributing sparingly over small lawns in the immediate vicinage 
of the dwelling-house. T. tricolorum, peregrinum, brachyceras, tuberosum, and 
even pentaphyllum, may all be made to increase "the charms of the pleasure- 
grounds, by a little attention, and the assistance of a frame in which to rear and 
protect them through the winter. T. tricolorum and brachyceras, being the most 
delicate, must be treated according to the common practice, observing to keep the 
bulbs or tubers perfectly dry in the winter, and not to start them by any artificial 
stimulus. The frame or trellis which they are intended to cover can be affixed to 
the outside of their pot, this last being furnished, of the precise size they are 
expected to require, in the early part of spring, at which time they should be 
repotted. When the season is sufficiently advanced to admit of their transference 
to the open ground without danger, they may be plunged to the rim in river sand 
or light soil, taking care to place a layer of ashes, two or three inches deep, at the 
bottom of the hole prepared for their reception, that no worms or other mining 
insects may find easy ingress from that quarter. 
It is quite incomprehensible to us how T. tricolorum, notwithstanding the 
facility with which it may be propagated and grown, should continue so scarce, 
and of such an unusual pecuniary value. We can only account for these circum- 
stances by surmising that it is treated too unnaturally, thereby occasioning the bulbs 
to rot and perish. No plant can suffer more injury from being induced to depart 
from the order of Nature, in regard to the time of commencing its growth, and the 
supply of water during its dormancy. Left to begin growing by its inherent 
impulses, neither over-potted nor watered immoderately in the summer, and kept 
entirely torpid through the winter season, it may be retained in perpetual health 
and vigour, and without manifesting the slightest appearance of disease or decay. 
To ensure the accomplishment of these ends, we cannot but believe that the 
adoption of the method above propounded would very materially tend ; and we 
would add, with especial emphasis, that the plants cannot be placed too high in 
the pot, provided the roots are not exposed to the atmosphere, nor can the pots be 
plunged too deeply in the soil, so that they are not actually buried. 
Respecting the multiplication of T. tricolorum, which may, in this point, be 
regarded as the type of all the other tender kinds, a few hints here may not be
