scape planting. As this is a Japanese species, however, it might be better 

 to use native Americnn Korts for strictly natural effects. 



Viburnum tomenfosum plicatuTn, Japanese Snowball. Tiie variety of the 

 foregoing which has flowers in a large round cluster like a popcorn ball. 

 Formerly this was rather po])ular, but in general it is not so good as the 

 doublefile viburnum. 



Viburnum venosum. Veiny Viburnum, ^'ery like dentatum in liabit of 

 growth and character of foliage and flowers though somewhat coarser. Its 

 special attraction is the abundance and bright blue color of its fruits in 

 autumn. It is fully hardy. 



T'/»ca minor, Common Periwinkle. A low-growing or prostrate hardy 

 vine, very tolerant of adverse conditions; will grow in shade or sun and on 

 dry or arid land. It is especially useful for ground cover in difficult situa- 

 tions. 



Vitis labrusca, Fox Grape. The native fox grape is hardy and may some- 

 times be used for purposes similar to the following species, though in general 

 its ornamental value is considerably less than that of the riverbank grape. 

 Other native species of grapes are satisfactory for landscape use in much the 

 same way as suggested below for the riverbank grape. 



Vitis vulfina, Riverbank Grape. A fine hardy, native vine, excellent for 

 general planting on pergolas, fences, or arbors, and very satisfactory for 

 growing over stone walls, cut banks, and similar positions. 



Weiffela rosea, Pink Weigela. A medium-sized, round-topped, neat hardy 

 shrub with good, showy flowers. They are generally quite popular for orna- 

 mental use on small lawns and similar home surroundings. They make fairly 

 good foundation plantings. Most of the plants on the campus are of the 

 composite group commonly listed as ir. hybrida — of uncertain parentage and 

 great variation in foliage and flower characters. 



Wisteria floribunda, Japanese Wisteria. A strong hardy vine and popu- 

 lar. Suitable for all sorts of locations where a heavy climber is desirable. In 

 this locality the species is particularly difficult to flower. While this disin- 

 clination toward flower-bearing seems to characterize the species widely, 

 there is apparently a tendency for it to be much more floriferous along the 

 seashore. Many suggestions have been made about bringing this vine into 

 better flowering habits, by pruning or change in feeding; but while some of 

 these methods have been tried here none has given satisfaction. 



Zanthorhiza apiifolia, Yellowroot. A dwarf shrubby plant, very hardy and 

 permanent, suitable for underplanting, for the margins of shrubberies, and 

 especially for holding banks against washing. Flowers inconspicuous, but 

 foliage clean and particularly good. 



Zanthoxylum americanum, Common Pkickley-ash. A hardy native species 

 of some value for garden and park planting, though seldom included in 

 nursery catalogs.
