TSUGA • Hemlock 



HE HEMLOCKS are a distinct and hardy group of evergreen, cone-bearing trees, re- 

 markable for their stately form. The hemlock is noted for its graceful branches and beauty 

 of foliage, which is a rich green on the upper surface and silvery below. Single trees on 

 the lawn or in the garden are always effective, but it is when they are grouped as they grow 

 in the wild they are most prized. It is then that we appreciate the ever-present, ever-chang- 

 ing play of light and shade and the constant movement and gentle sighing of breezes 

 through the lovely, feathery branches. The hemlocks stand shearing well and form an 

 unusual and serviceable hedge. As a curtain of green in the garden background they 

 enhance the beauty of even the showiest blooms. 



^Jduaa canadensis 

 (Canada ^Jdemfocl? 



Native from Wisconsin south to 

 northern Georgia. Usually gregarious 

 in a wild state in gulches and val- 

 leys where moisture is abundant jnd 

 drainage natural. One of the most 

 graceful conifers. Slender, drooping 

 branches are covered with foliage of 

 a distinct, characteristic and pleasing 

 shade of green. In a well-developed 

 specimen the lights and shadows are 

 displayed effectively. Although it 

 grows to a large size it is a relatively 

 slow grower and makes a perfect lawn 

 tree. Will thrive in shade and because 

 it stands shearing it may be used for 

 the making of beautiful hedges or 

 screens. 



TSUGA canadensis globosa (Globe Canada 

 Hemlock) . A low plant with upright branches nod- 

 ding at the ends. Dark green. Well adapted to restricted 

 situations in the garden. 



T. canadensis gracilis ( Slender Canada Hem- 

 lock). A slow growing Hemlock with very small 

 dark green leaves and slender, spreading branches that 

 droop slightly at the ends. 



T. canadensis pendula (Sargent Weeping Hem- 

 lock). A weeping form of the Canadian Hemlock. 

 Grows into a perfect flat-topped mound with spread- 

 ing branches and gracefully drooping branchlets. 



T. caroliniana (Carolina Hemlock). A native 

 from the Blue Ridge Mountains to northern Georgia. 

 Very distinct in its character from the common Hem- 

 lock. A smaller growing tree, it has a more com- 

 pact habit of growth. Very dark green foliage. In 

 the autumn when its branches are loaded with the 

 yellowish-brown cones it is an object of singular 

 beauty. Hardy, prefers a cool, moist, well-drained soil. 



T. diversifolia (Japanese Hemlock). Forms a 

 bushy tree with short, narrow, attractive foliage. 

 Conspicuous white lines on under sides of the leaves 

 contrast pleasantly with the dark green of the upper 

 surfaces. A graceful and handsome species. 



T. sieboldi (Siebold Hemlock) . Another beautiful 

 contribution from the Orient. Forms a graceful, 

 bushy tree with slender, spreading branches, attrac- 

 tive, dark, glossy green foliage. 



Sargents Hemlock 

 (Tsitga sargenti), an 

 "Aristocrat of the 

 Garden" contrasts, 

 strikingly with the 

 feather gray - green 

 foliage of C e d r u s 

 atlantica glauca, in 

 the background at 

 the right.
