114 THE CULTIVATED EVERGREENS 



allies are mostly propagated from seeds, cuttings, and layers. 

 The seed is hard to sprout and requires two to three years 

 for germination. When propagated from cuttings, a gentle 

 bottom heat is required. It is best done under glass, taking the 

 cutting from nearly ripened wood in the early fall. Stool 

 cuttings are preferable for those varieties with scale-like leaves. 

 These are also increased by side grafting in the winter on 

 previously potted plants of allied species. Copious watering 

 overhead is essential until the graft is set. The plants pro- 

 pagated by layers in early fall require gentle bottom heat. -' 



Juniperus virginiana var. glauca is a distinct blue type of 

 pyramidal habit. The young growth is almost silvery-white, 

 changing to a beautiful bluish-green in winter. For landscape 

 effect it is excellent. It is perfectly hardy, of compact growth, 

 and thrives in a rich clay loam. Propagation is by grafting 

 on J. virginiana. Var. Schottii is planted for its pyramidal, 

 compact growth and extreme hardiness. It is propagated from 

 cuttings. Var. Canaertii is a pyramidal compact form attaining 

 a height of fifteen to eighteen feet. The foliage is dark green. The 

 plant is useful for planting in formal and natural gardens and its 

 silver-colored fruit is attractive. It does well in any ordinary 

 garden soil and is propagated from cuttings and grafting. 



Juniperus communis var. depressa has many branches and 

 seldom exceeds five feet in height. It thrives best in a sandy or 

 gravelly soil and is extremely hardy and a rapid, vigorous 

 grower. The foliage is grayish-green, light silvery-green be- 

 neath. It is propagated from seeds and cuttings. Landscape 

 planters make use of it to cover unsightly spots and as an 

 edging to taller trees. Fruit of this variety matures the third 

 year when it is used for medicinal purposes and manufacturing 

 of spirits. Var. aurea is a golden form. It is hardy and useful 

 for color effect with other junipers.
