of the native Hemlock. As a mature specimen, its lacy outline, dark foliage, 

 and attractive cones make it interesting and valuable. In small sizes it does 

 not transplant as readily as the native species. Like the Canada Hemlock, 

 garden varieties are now being selected and tested. 



Tsuga diversifolla JAPANESE HEMLOCK 



Usually seen in cultivation as a bushy, multiple-leadered specimen with 

 interesting, dark, shining foliage having prominent stomatic bands beneath. 

 It is slow growing and difficult to transplant while young. Not a plant for 

 liberal planting use.

Twinflower — See Linnaea 



ULMUS AMERICANA American Elm 



A significant fact about this most familiar of all trees is the way in which 

 it has been able to forget its native alluvium and thrive under difficult street 

 conditions. Whether or not serious insect enemies and the Dutch elm disease 

 will tend to make the use of Elms imprudent, remains to be determined. In 

 nature the Elm takes on numerous different habits, one of which is shown in 

 the "MOLINE ELM" which grows rapidly into a loose column. 



Ulmus foliacea var. Wheatleyi JERSEY Elm 



A columnar form of the smooth-leaf Elm. 



ULMUS PARVIFOLIA CHINESE Elm 



A thin-branched, open-headed tree with small leaves which turn red or purple 

 in autumn. Not to be confused with the faster-growing, less desirable U. pum- 

 ila. 



ulmus procera (U. campestris) English Elm 



A large tree which has numerous cultivated varieties. Because it retains 

 its leaves longer in the autumn and, in general, thrives under trying conditions, 

 it has long been considered valuable as a street tree. 



Umbrella Pine — See Sciadopitys 



VACCINIUM CORYMBOSUM Highbush Blueberry 



Though capable of growing much taller, this familiar native species is 

 usually seen in cultivation as a broad, twiggy, deciduous shrub up to about 

 six feet. Its general rugged aspect, its brilliant autumn foliage display, and 

 the winter interest of its yellow-green or red twigs give it claim to more exten- 

 sive use in roadside planting or other informal grouping. Its many pomo- 

 logical forms differ only in size and quality of fruit. Its berries offer attraction 

 to birds. Forms based on habit or leaf coloration are in cultivation. 



Vaccinium macrocarpum CRANBERRY 



In moist, peaty places in wild gardens, this familiar economic plant has 

 possibilities as ground-cover material. It is particularly interesting in autumn 

 while in fruit. 



VACCINIUM PENNSYLVANICUM LOWBUSH BLUEBERRY 



A variable deciduous shrub of dry or barren hills, which seldom reaches 

 more than two feet in height. Useful as a ground cover or for bank planting. 

 Fruit edible.
