THE ORNAMENTAL PLANTS — CLIMBERS 307 
6. CurmBina PLANTS 
Vines do not differ particularly in their culture from other 
herbs and shrubs, except as they require that supports be pro- 
vided; and, as they overtop other plants, they demand little 
room on the ground, and they may therefore be grown in narrow 
or unused spaces along fences and walls. 
In respect to the modes of climbing, vines may be thrown 
into three groups, — those that twine about the support; those 
that climb by means of special organs, as tendrils, roots, leaf- 
stalks; those that neither twine nor have special organs but 
that scramble over the support, as the climbing roses and the 
brambles. One must recognize the mode of climbing before 
undertaking the cultivation of any vine. 
Vines may also be grouped into annuals, both tender (as 
morning-glory) and hardy (as sweet pea); biennials, as adlumia, 
which are treated practically as annuals, being sown each year 
for bloom the next year; herbaceous perennials, the tops dying 
each fall down to a persisting root, as cinnamon vine and 
madeira vine; woody perennials (shrubs), the tops remaining 
alive, as Virginia creeper, grape, and wistaria. 
There is scarcely a garden in which climbing plants may not 
be used to advantage. Sometimes it may be to conceal obtru- 
sive objects, again to relieve the monotony of rigid lines. They 
may also be used to run over the ground and to conceal its 
nakedness where other plants could not succeed. The shrubby 
kinds are often useful about the borders of clumps of trees and 
shrubbery, to slope the foliage down to the grass, and to soften 
or erase lines in the landscape. 
In the South and in California, great use is made of vines, 
not only on fences but on houses and arbors. In warm coun- 
tries, vines give character to bungalows, pergolas, and other 
individual forms of architecture. 
If it is desired that the vines climb high, the soil should be
