HEMLOCK * TSUGA

---

• Ornamental trees grown chiefly for their graceful habit and handsome foliage. Nine or ten species in North American, E. Asia and the Himalayas. Closely allied to Abies and Picea.
   
• The hemlock spruces are evergreen trees of pyramidal habit, with spreading irregularly whorled much ramified branches. There are probably no more beautiful hardy conifers than the hemlocks, and they must be ranked among the most ornamental and useful trees for park planting. They do not have the stiff formal appearance of many of the conifers, but are graceful and stately at the same time.
   
• Bears pruning well. Not very particular as to the soil, provided it contains a sufficient amount of constant moisture.
   
• Varieties grow to 100 ft.
