Ivy is generally, I believe, known to gardeners as a creeping 
dependant plant only ; but when the trees have acquired a 
considerable age, and have produced fruit-bearing branches, 
these exhibit an independant form of growth, which they retain 
when detached, and form very hardy evergreen shrubs of low 
stature. If these were intermixed with plants of the more 
delicate varieties of the Chinese rose, or other low deciduous 
and somewhat tender-flowering shrubs, so that the stems of the 
latter would be covered in the winter, whilst their foliage would 
be fully exposed to the light in summer, I think it probable 
that those might be successfully cultivated in situations where 
they would perish without such protection; and the evergreen 
foliage of the ivy plants in winter would be generally thought 
ornamental. Detached fruit-bearing branches of ivy readily 
emit roots, and the requisite kind of plants would therefore be 
easily obtained. 
199 Greenhouse Shrubs, for Walls. Having, at section 190 
of the Auctarium, given a list of greenhouse and half-hardy 
free-flowering plants, suitable for turning into the open ground, 
in the month of May, with directions concerning their man- 
agement, we now proceed to give a list of the hard-wooded 
and less free-flowering greenhouse plants, for planting against 
an open wall. These, to be seen in perfection, must be 
preserved for years, by some slight protection, every winter; 
such as fern, spruce fir, branches of broom, &c., according 
as one or the other may be conveniently obtained. The cover- 
ing should not, however, prevent light being admitted to the 
plants, otherwise they will be likely to suffer upon the covering 
being removed. As most of the plants about to be recom- 
mended ripen their wood in autumn, and remain dormant 
during winter, they endure much more cold, without injury, 
than those recommended for the flower-beds; which, from 
their succulent nature, are sometimes destioyed by the first 
sharp frost of autumn. The wall for planting against should 
have a border prepared in front of it, four feet wide, by mixing 
a portion of peat and sand, with the common soil, to the depth 
of two feet and a half, the bottom being first made perfectly dry. 
The plants should be hardened gradually, as recommended in 
section 190, and turned out against the wall in the latter end of 
May, at such a distance from each other as the different species
