\ a< vi niuin Vitis-idaea COWBERRY 



A low (twelve inches), spreading, evergreen shrub which has rounded shining 

 leaves, white flowers in spring, and dark red berries. An excellent rock-garden 

 shrub offered by the trade in two forms. Var. majus has larger leaves and 

 fruits. Var. MINUS, the Mountain Cranberry, is perhaps half as tall as 

 the type and, likewise, smaller in other parts. 



Viburnum acerifolium Maple-Leaf VlBTJRNUM 



Though not of garden value for flowers or fruit, this native deciduous shrub 

 is useful for bank planting in association with large woodland trees. In the 

 open it will get to be six feet high and put on a bright crimson foliage show in 

 autumn. 



VIBURNUM CARLESII FRAGRANT VlBURNUM 



A broad, spreading, deciduous shrub to five feet, with rounded grayish 

 leaves and dense, three-inch cymes of white, fragrant flowers with the leaves 

 in late April or early May. The fruits are blue-black and not showy. It has 

 suffered in cultivation because (seeds being scarce and cuttings slow) of the 

 questionable practice of grafting on rootstocks of other species. Because of 

 inevitable wild suckering and possible lack of affinity for the understock, own- 

 root plants are much to be preferred. 



Viburnum cassinoldes WlTHE-RoD 



A tall (six to fifteen feet), native, deciduous shrub of moist land, which was 

 much used in the past in large border plantings. Its leaves are relatively small, 

 plentiful and of shining green. The fruit changes through pink to black. A 

 good thing for suitable roadside locations. 



VIBURNUM DENTATUM ARROW-WOOD 



A tall (ten feet or more at maturity), broad, bushy, deciduous shrub with 

 lustrous, rounded, toothed leaves. Its conspicuous white flowers in three-inch 

 flat heads in late May or early June are followed in autumn by blue-black 

 fruits. Will withstand considerable shade. Fruit eaten by birds. 



VIBURNUM DILATATUM Linden Vibburnum 



A broad, tall (ten feet or more at maturity), deciduous shrub with rounded, 

 toothed leaves. The white flowers in flattened clusters in late May or early 

 June are followed in autumn by showy, persistent, scarlet fruits. Var. xan- 

 thocarpum has yellow fruits. 



VIBURNUM FRAGRANS 



An upright, deciduous shrub to some nine feet in height with toothed, wedge- 

 shaped leaves on short, colored petioles. The garden value of this plant lies 

 in its small, fragrant, white flowers which open from pinkish buds in April or 

 early May before the leaves appear on the plant. 



Viburnum Lantana WayFARING-Tree 



A rather rapid-growing, tall (fifteen feet), often tree-like, deciduous shrub 

 with five-inch, finely toothed, hairy, long-persistent leaves. The white flowers 

 of late May or early June are followed by red fruits which eventually turn 

 black. A plant which can be used to advantage in certain dry situations. 

 Much used of late years as an understock for V. Carlesii. 



Viburnum prunifolium BlaCK-HaW 



A large, bare-based, deciduous shrub or small, multiple-stemmed tree up to 

 some fifteen feet in height. The broad, rounded head of the plant is covered 

 in late April or early May with relatively large, white flower clusters which
