PLANTING 



PLANTING 



Shrubs, small trees, and woody vines hardy in the 

 northeastern United States. 



The use of shrubs in landscape planting is explained 

 in the preceding articles of this symposium on Planting. 

 The illustrations, Figs. 3048 to 3060 inclusive, indicate 

 the habit of some of the species. 



1 before name means plant is low, 6 inches to 2 feet. 



2 means plant is small, 3 to 5 feet. 



3 means plant is medium, 6 to 8 feet. 



4 means plant is large, 10 to 15 feet. 



D means dioecious, i. e., only one sex on a plant. Fruiting (i. e., 

 pistillate) plants must be secured with also one or more pollen- 

 bearing (i. e. staminate) plants. 



E means plant is evergreen. 



e means plant is good for edging (low, neat, and compact). 



G means plant is good ground-cover (trailing or creeping). 



H means plant is hedge material. 



P means requires protection in climate of Boston. 



5 means semi-evergreen (holding leaves till December or later). 

 V means plant is a vine.

 characteristic form.

protected may be cut to ground annually). 



&H2 Buxus japonica (a new and hardy box; will probably 

 reach 8 feet but is slow-growing and easily restrained 

 by clipping). 

 EHP2 Buxus sempervirens (must be protected in the North, 



but is hardy and tree-like in the South). 

 Kofi Buxus sempervirens var. suffruticosa. 

 1 Callicarpa japonica. 



1 Callicarpa purpurea. Both of these callicarpas are 

 wot /-< ,J ender a ? d require cutting back early in spring. 

 EeGl Cal una vulgaris. Succeeds best in United States if 

 kept low and vigorous by heavy pruning early in 

 spring. Flowers appear in summer.

V Campsis radicans. 

 2 Campsis radicans var. speciosa. 

 3 Caragana frutex.

H4 Carpinus Betulus. Dense slow-growing tree, much used 

 for hedges. Better than the native hornbeam, C. 

 caroliniana. 



H3 Carpinus Betulus var. globosa. This is an upright, oval 

 form of the above. It is very dense and compact 

 and may reach 15 to 20 feet in height, but is very 

 slow-growing and can be restrained easily. See page 

 2683. 



2 Catalpa bignonioides var. nana. This is known in the 

 trade as C. Bungei, but is not the true C. Bungei 

 from China. It is a dwarf variety of the southern 

 catalpa (C. bignonioides). It is often grafted high 

 on an upright stem, but if grown on its own roots it 

 will make only a dense round bush.

 V Celastrus scandens. 

 i Cephalanthus occidentals. 

 4 Cercis canadensis. 

 H2 Chaenomeles japonica. 



1 Chaenomeles Maulei. 



EH4 Chamsecyparis nootkatensis. This is a large timber tree 

 of the north Pacific coast. It is hardy, but little 

 known in the East. Its good qualities are compact 

 oval shape and dense soft foliage. It is also slow- 

 growing and may be restrained easily for small- 

 scale planting. See page 2683. 

 E4 Chamsecyparis obtusa. 



EH2 Chamsecyparis obtusa var. nana. This is the finest of 

 the Japanese cypresses (Chamsecyparis), all of 

 which were originally introduced in the trade under 

 the name Retinospora. This form will reach 6 to 8 

 feet, but is dwarf and very slow-growing and can 

 be restrained easily. Its f9liage is small and blunt, 

 dark green above with white Y-shaped lines below. 

 The spray is in compact, concave, fan-shaped masses 

 arranged laterally, producing very interesting hori- 

 zontal lines and shadows.

 adpressa and better as ground-cover in rock-garden). 

 2 -Cotoneaster racemiflora. 

 2 Cotoneaster Simonsii. 

 2 Cotoneaster tomentosa. 



H4 Crataegus coccinea. All these thorns are better as natural 

 screens with room to spread at the bottom than
