the White Banksia. A good substitute for Maré- 
chal Niel, although not its equal, is the yellow 
Gloire de Dijon. The best red is Riene Marie 
Henriette. The Cherokee rose (R. laevigata), a 
tender, bushy, white species orginally from the 
Orient, but now naturalized in the South, can 
also be forced in the cool house with good results. 
One of the grandest flowering vines we have 
for a greenhouse where the temperature does 
not fall below 50°, is the potato vine (Solanum 
jasminoides). This plant produces large clusters 
of flowers an inch across, white with a tinge of 
blue. It should be planted out in the border, 
generously fed while in growth, and sprayed 
often, except when in flower. It is a twiner, but 
should be trained nevertheless. As it flowers 
on new wood, it should be pruned just before it 
starts to grow, usually in March, after a winter’s 
rest. Under favourable conditions it will attain 
a height of twenty feet. A larger-flowered form 
is S.jasminoides var. grandiflorum, while S. jas- 
minoides var. variegatum has variegated foliage. 
A vast improvement on the potato vine is 
found in Solanum Wendlandit, which is a more 
vigorous grower, able to attain a height of fifty 
feet. The flowers, produced in immense clusters, 
are about two and one half inches across and pale
