Vines are really climbing plants. They get up 

 world in three general ways: by scrambling or clam- 

 bering over other plants without any s]ir(-ial devices 

 for aiding them in the ascent: l.y twining almut the 

 support; by ascending by means ..f -|.i .lal iiiyans, as 

 roots or tendrils. The larger iiiiinl.. i- ,.i .ultivated 

 climliinpr plants belong to tin- last iwi. .-ategories.

stiniiii. il ruses. These plants usually have tu lie tied to 

 a support unless they are allowed to ramble at will over 

 some expanded surface, as the top of a bush or a broad 

 stone wall. 



Each species of twining plant has its own direction of 

 winding about the support, and the species follows this 

 direction under all ordinary circumstances. Some of 

 them, as the hops, wind about the support in the direc-

VINES. In horticultural parlance, a vine is a weak- 

 stemmed, more or less tail-growing plant that needs to 

 have the support of some rigid object to hold it above 

 the earth. Many plants that are grown for their eco- 

 nomic uses are vines, althouL'h tliev are cinlinarily not 

 so classified in horticultural \\..ik., |..i , \aiiiple, some 

 of the beans, the hop and till ilaiit. When

 them are valu.-d clii.ijy for foliage, as the Virginia 

 creeper, Japanese ivy, grapes and the true or English 

 ivy; others are prized largely for their flowers, as morn- 

 ing-glories, moonflowers and scarlet runners. Vines 

 represent all degrees of hardiness or tenderness; they 

 are also of various heights and differ in rapidity of 

 growth ; therefore it is impossible to make a list of vines 

 that shall apply to the whole country.
