ON TREES AND SHRUBS. 485 



C. a.fastigiata is an erect-growing, glaucous-leaved variety, of close 

 habit, and well adapted for planting in positions where the type 

 would be inadmissible on account of the spread of its branches. 

 C. a. glauca is similar in habit to the type, with glaucous leaves, 

 which, when associated with trees having deep green foliage, are 

 seen to great advantage. It has a vigorous leader, and its 

 branches droop gracefully with age. This is specially useful for 

 decorative planting. C. Deodara (see page 478). C. D. erecta 

 differs from the sacred Cedar by reason of its more upright 

 habit, short, stiff branches, and beautiful glaucous leaves. 

 C. D. robusta is a free-growing variety of distinct habit, with 

 larger leaves than the type. It is rather sparsely supplied with 

 branches, which are given off horizontally, the lower ones 

 sweeping the ground, and with age they all assume a weeping 

 habit. Of free growth, it is a useful, ornamental tree, and as it 

 is rather late in commencing to grow, is less liable to damage 

 from late frosts than are its congeners. C. D. variegata differs

from' the type because a number of its young growths and leaves 

 are creamy-white in colour. C. £>. verticillata has short branches 

 clothed with glaucous leaves ; it is of rather drooping habit, and 

 slow in growth. C. D. viridis is also of graceful, weeping habit, 

 with long, slender branches, but in this case the leaves are of a 

 rich grass-green. 



C. Libani (Cedar of Lebanon) (Fig 310) is a noble park tree, 

 which has been cultivated here since 1683. It is of good growth 

 and distinct habit, reaching to a height of 80ft., with a spread of 

 branches frequently 50ft. The cones are about 4in. long, and 

 are borne with great freedom. No soil, however poor, comes amiss 

 to this picturesque tree, but it grows more rapidly when planted 

 where its roots are within easy reach of water, such as by the 

 margins of lakes. A grand tree for the landscape, and many fine 

 examples are to be found in English gardens. 



The species of Cedars are increased by seeds, which may be 

 sown in cold frames in spring in well-drained soil, the seeds
