VITIS LABRUSCA Fox Grape 



As seen clambering over shrubs, small trees, and fence rows, this native 

 wild Grape becomes one of the pleasant features of our New England road- 

 sides, and should be more used in wilder areas where it need not be confined. 

 Despite cultivated forms, the thick-skinned, sweetish, musky-tasting fruit is 

 valued by some for wine or jelly making. The fruits are also eaten by grouse, 

 pheasant and deer. 



VITIS VULPINA RlVEBBANK GRAPE 



A native, vigorous climber which, in addition to its pleasing foliage, has 

 appeal because of fragrance of male flowers.

WISTERIA FLORIBUNDA Japanese Wisteria 



This species is considered to be superior to W. sinensis, with which it is 

 confused in gardens, because of greater hardiness and longer, violet-colored 

 flower clusters. There are numerous garden varieties which, to be true to 

 name, must be propagated vegetatively. That grafting from flowering plants 

 will always insure early flowering remains to be proved. Though generally 

 used as a high-climbing, deciduous vine, Wisteria has great value when grown 

 on low supports or as a well-pruned, runnerless, large shrub. Good forms other 

 than the type are var. alba, white flowering form with long racemes (up 

 to eighteen inches), which lose their effectiveness if used against the back- 

 ground of a white house; var. MACROBOTRYS (W. multijuga), Long- 

 cluster Wisteria, blue-violet flowers in racemes sometimes up to a yard in 

 length; var. violaceo-plena, for those who wish darker, double flowers. 



Wisteria nankinensis DWARF WlSTERIA 



A very dwarf Wisteria which in the rock garden builds up into a quite sym- 

 metrical small bush. Its flowers have not yet been seen in American gardens.

Xanthoceras sorblfolia 



A heavy-wooded, deciduous shrub or small tree which, at times, grows to a 

 height of fifteen feet or more. It is planted because of its showy racemes of 

 white flowers in May; also, because of its shining, persistent, compound leaves 

 with toothed leaflets. 



XANTHORRHIZA SIMPLICISSIMA (X. apiifolia) Yellowroot 



A deciduous shrub with upright stems to about two feet. Spreads by suckers 



to make a solid ground cover. Its interesting compound leaves unfold with 



the opening of the terminal, drooping, purplish flowers in early spring. While
