THE ORNAMENTAL PLANTS — CLIMBERS 309 
add the best of them to his collection. Most of these natives 
are worthy of cultivation. Even the poison ivy makes a very 
satisfactory cover for rough and inaccessible places in the wild, 
and its autumn color is very attractive; but of course its culti- 
vation cannot be recommended. 
Vines that cling closely to walls of buildings are Virginia 
creeper (one form does not cling well), Boston or Japanese ivy 
(Ampelopsis tricuspidata; also A. Lowii, with smaller foliage), 
English ivy, euonymus (£. radicans and the var. vartegata), and 
Ficus repens far south; others that cling less closely are 
trumpet creeper, and climbing hydrangea (Schizophragma hy- 
drangeoides). 
Vines for trailing, or covering the ground, are periwinkle 
(Vinca), herniaria, moneywort (Lysimachia nummularia), 
ground-ivy (Nepeta Glechoma), Rosa Wichuraiana, species of 
native greenbrier or smilax (not the so-called smilax of florists), 
Rubus lacintatus, dewberries, and also others that usually are not 
classed as vines. In the South, Japanese honeysuckle and © 
Cherokee rose perform this function extensively. In California, 
species of mesembryanthemum (herbaceous) are extensively 
used as ground covers on banks. Page 86. 
For quickly covering brush and rough places, the many kinds 
of gourds may be used; also pumpkins and squashes, water- 
melons, Cucumis foctidissima, wild cucumbers (Echinocystts lobata 
and Sicyos angulata), nasturtiums, and other vigorous annuals. 
Many of the woody perennials may be used for such purposes, 
but usually these places are only temporary. 
For arbors, strong woody vines are desired. Grapes are ex- 
cellent; in the South the muscadine and scuppernong grapes are 
adaptable to this purpose (Plate XV). Actinidia and wistaria 
are also used. Akebia, dutchman’s pipe, trumpet creeper, 
clematis, honeysuckles, may be suggested. Roses are much 
used in warm climates. 
For covering porches, the standard vine in the North is Vir-
