VINES FOR THE COOL HOUSE 175 
it to cover. A péculiarity of the vine is that, 
when a branch bears fruit, it loses all the character- 
istics of the plant, grows out from the support, 
develops larger leaves and shows no inclination 
to climb. In fact, one would never recognize 
it as a part of the original stem. 
A smaller-leaved variety is F. pumila var. 
minima, which I rather prefer for back walls, for 
the very small leaves, thickly set, make a very 
attractive wall cover. Both vines will attain a 
height of ten feet. They require a night tem- 
perature not lower than 55° in winter. 
For a house that cannot be kept above 45° 
in winter, the best flowering vine is the ever- 
green cross vine (Bignoniacapreolata). The abun- 
dant, tubular, yellowish-red blossoms have given 
this vine the additional, though less common, 
name of trumpet vine. - 
Differing from most vines, bignonia should 
have its root space restricted for best results. 
It is therefore often grown in a large box placed 
under the staging in the cool house. It must be 
fed freely when the flowering stems are growing. 
Heavy pruning is required and also a daily spray- 
ing except during the flowering period. To ward 
off the mealy bug, spray once a fortnight with 
a strong kerosene emulsion or tobacco decoction.
