110 THE CULTIVATED EVERGREENS 



ordinary good soil, but does especially well in a damp, cool, 

 clay loam. It does not always come true from seed and is 

 usually propagated from cuttings taken in early fall, with 

 gentle bottom heat in frames or greenhouse. The cuttings 

 should be kept cool until callousing takes place, when heat 

 both in bottom and top can gradually be increased. Cuttings 

 should be shaded from the direct sun, watered freely overhead, 

 and given plenty of air. Var. Douglasii pyramidalis has feathery, 

 lace-like, crested foliage of a dark green color. The habit is 

 pyramidal. It is of slow growth, to about eighteen to twenty 

 feet high, and is perfectly hardy and grows well in moist clay 

 loam. Var. lutea, Peabody golden arbor-vitse, is a distinct 

 bright golden type. It is of rather slender growth, twelve to 

 fifteen feet high. It grows best in clay loam. On account of its 

 brilliant golden hue, it is useful where color effect is desired. 

 Var. alba has silvery white-tipped foliage, forming a pleasing 

 contrast to the otherwise dark green leaves. It varies in habit 

 from a low compact growth to a loose, feathery, pyramidal 

 bush, and is hardy and easily propagated from cuttings or by 

 grafting. Var. rohusta, Siberian arbor-vitse, is a very beautiful, 

 dark green, conical type. Its habit is distinct and its branches 

 short and stiff. The foliage is a dark sea-green. It is of rugged 

 constitution and perfectly hardy, but of slow growth. It is 

 propagated from cuttings. Var. Woodwardii is one of the best 

 globe-shaped arbor- vitaes. It maintains its shape without 

 artificial means. The color of foliage is a pleasing sea-green. 

 It grows about three feet high and is as hardy as the species. 

 Var. Hoveyi is a very pretty, dwarf, compact form, with yellow- 

 ish-green foliage. The habit is globose. It is hardy in southern 

 Wisconsin, Minnesota, and other western States and is useful 

 for low planting in front of other taller-growing plants. It 

 is propagated from cuttings. The soil requirement is a moist
